| * | move F_DUPFD_CLOEXEC out of bits•••fcntl values 1024 and up are universal, arch-independent. later I'll
add some of the other linux-specific ones for notify, leases, pipe
size, etc. here too.

| * | rename __sa_restorer to sa_restorer in struct sigaction•••this is legal since sa_* is in the reserved namespace for signal.h,
per posix. note that the sa_restorer field is not used anywhere, so
programs that are trying to use it may still break, but at least
they'll compile. if it turns out such programs actually need to be
able to set their own sa_restorer to function properly, i'll add the
necessary code to sigaction.c later.

| * | fix alloca issue in stdlib.h too•••I forgot _GNU_SOURCE also has it declared here...
| Rich Felker | 2012-04-09 | 1 | -1/+1 |
| * | alloca cannot be a function. #define it to the gcc builtin if possible•••gcc makes this mapping by default anyway, but it will be disabled by
-fno-builtin (and presumably by -std=c99 or similar). for the main
program the error will be reported by the linker, and the issue can
easily be fixed, but for dynamic-loaded so files, the error cannot be
detected until dlopen time, at which point it has become very obscure.

| * | remove useless (at best, harmful) feature test checks in aio.h | Rich Felker | 2012-04-03 | 1 | -5/+0 |
| * | optimize signbit macro | Rich Felker | 2012-03-30 | 1 | -2/+2 |

| * | simplify creal and cimag macros | Rich Felker | 2012-03-22 | 1 | -8/+8 |
| * | add creal/cimag macros in complex.h (and use them in the functions defs) | Rich Felker | 2012-03-22 | 1 | -0/+11 |
| * | tgmath.h: suppress any existing macro definitions before defining macros•••this is necessary so that we can freely add macro versions of some of
the math/complex functions without worrying about breaking tgmath.
| Rich Felker | 2012-03-22 | 1 | -0/+63 |
| * | fix DECIMAL_DIG definitions•••DECIMAL_DIG is not the same as LDBL_DIG
type_DIG is the maximimum number of decimal digits that can survive a
round trip from decimal to type and back to decimal.
DECIMAL_DIG is the minimum number of decimal digits required in order
for any floating point type to survive the round trip to decimal and
back, and it is generally larger than LDBL_DIG. since the exact
formula is non-trivial, and defining it larger than necessary may be
legal but wasteful, just define the right value in bits/float.h.

| * | initial, very primitive strfmon | Rich Felker | 2012-03-21 | 1 | -0/+21 |
| * | limits.h: support gcc's -funsigned-char•••some software apparently uses this and breaks with musl due to
mismatching definitions...
| Rich Felker | 2012-03-20 | 1 | -2/+10 |
| * | move nonstandard gamma() etc. to _GNU_SOURCE only•••it's not even provided in the library at the moment, but could easily
be provided with weak aliases if desired.
| Rich Felker | 2012-03-17 | 1 | -4/+4 |
| * | c++ seems to want some casts in the float representation-access macros | Rich Felker | 2012-03-17 | 1 | -2/+2 |
| * | in math.h make lgamma_r and non-double bessel _GNU_SOURCE only•••long double and float bessel functions are no longer xsi extensions

| * | efficient sincos based on sin and cos | nsz | 2012-03-15 | 1 | -0/+4 |
| * | first commit of the new libm!•••thanks to the hard work of Szabolcs Nagy (nsz), identifying the best
(from correctness and license standpoint) implementations from freebsd
and openbsd and cleaning them up! musl should now fully support c99
float and long double math functions, and has near-complete complex
math support. tgmath should also work (fully on gcc-compatible
compilers, and mostly on any c99 compiler).
based largely on commit 0376d44a890fea261506f1fc63833e7a686dca19 from
nsz's libm git repo, with some additions (dummy versions of a few
missing long double complex functions, etc.) by me.
various cleanups still need to be made, including re-adding (if
they're correct) some asm functions that were dropped.

| * | fix nan/infinity macros in math.h, etc.•••the previous version not only failed to work in c++, but also failed
to produce constant expressions, making the macros useless as
initializers for objects of static storage duration.
gcc 3.3 and later have builtins for these, which sadly seem to be the
most "portable" solution. the alternative definitions produce
exceptions (for NAN) and compiler warnings (for INFINITY) on newer
versions of gcc.

| * | typo in math.h c version check | Rich Felker | 2012-03-02 | 1 | -1/+1 |
| * | make math.h compatibe with c89 | Rich Felker | 2012-03-02 | 1 | -1/+5 |
| * | add all missing wchar functions except floating point parsers•••these are mostly untested and adapted directly from corresponding byte
string functions and similar.
| Rich Felker | 2012-03-01 | 1 | -0/+15 |
| * | add memory.h, bogus legacy alias for string.h | Rich Felker | 2012-03-01 | 1 | -0/+1 |
| * | use c++-friendly initializers for pthread initializer definitions•••these will also avoid obnoxious warnings with gcc -Wbraces.
| Rich Felker | 2012-02-29 | 1 | -3/+3 |
| * | add <syscall.h> as an alias for <sys/syscall.h>•••apparently some broken stuff (libstdc++) needs this.
| Rich Felker | 2012-02-29 | 1 | -0/+1 |
| * | replace prototype for basename in string.h with non-prototype declaration•••GNU programs may expect the GNU version of basename, which has a
different prototype (argument is const-qualified) and prototype it
themselves too. of course if they're expecting the GNU behavior for
the function, they'll still run into problems, but at least this
eliminates some compile-time failures.

| * | add get_current_dir_name function | Rich Felker | 2012-02-17 | 1 | -0/+1 |
| * | add float_t and double_t to math.h | Rich Felker | 2012-02-15 | 1 | -0/+2 |
| * | replace bad cancellation cleanup abi with a sane one•••the old abi was intended to duplicate glibc's abi at the expense of
being ugly and slow, but it turns out glib was not even using that abi
except on non-gcc-compatible compilers (which it doesn't even support)
and was instead using an exceptions-in-c/unwind-based approach whose
abi we could not duplicate anyway without nasty dwarf2/unwind
integration.
the new abi is copied from a very old glibc abi, which seems to still
be supported/present in current glibc. it avoids all unwinding,
whether by sjlj or exceptions, and merely maintains a linked list of
cleanup functions to be called from the context of pthread_exit. i've
made some care to ensure that longjmp out of a cleanup function should
work, even though it is not required to.
this change breaks abi compatibility with programs which were using
pthread cancellation, which is unfortunate, but that's why i'm making
the change now rather than later. considering that most pthread
features have not been usable until recently anyway, i don't see it as
a major issue at this point.

| * | fix typo in inotify.h | Rich Felker | 2012-02-07 | 1 | -1/+1 |
| * | declare basename in string.h when _GNU_SOURCE is defined•••note that it still will have the standards-conformant behavior, not
the GNU behavior. but at least this prevents broken code from ending
up with truncated pointers due to implicit declarations...
| Rich Felker | 2012-02-07 | 1 | -0/+1 |
| * | revert hacks for types of stdint.h integer constant macros•••per 7.18.4: Each invocation of one of these macros shall expand to an
integer constant expression suitable for use in #if preprocessing
directives. The type of the expression shall have the same type as
would an expression of the corresponding type converted according to
the integer promotions. The value of the expression shall be that of
the argument.
the key phrase is "converted according to the integer promotions".
thus there is no intent or allowance that the expression have
smaller-than-int types.

| * | more locale_t interfaces (string stuff) and header updates•••this should be everything except for some functions where the non-_l
version isn't even implemented yet (mainly some non-ISO-C wcs*
functions).
| Rich Felker | 2012-02-06 | 3 | -0/+15 |
| * | fix some omissions and mistakes in locale_t interface definitions | Rich Felker | 2012-02-06 | 1 | -0/+24 |
| * | add more of the locale_t interfaces, all dummied out to ignore the locale | Rich Felker | 2012-02-06 | 1 | -0/+5 |
| * | add deprecated (removed from posix) [efg]cvt() functions•••these have not been heavily tested, but they should work as described
in the old standards. probably broken for non-finite values...
| Rich Felker | 2012-02-06 | 1 | -0/+3 |
| * | apparently gnu caddr_t is supposed to be char *, not unsigned long•••this type should never be used anyway, but some old junk uses it..

| * | add MIN/MAX macros to sys/param.h•••this is a nonstandard junk header anyway, so just do what apps expect..
| Rich Felker | 2012-01-24 | 1 | -0/+5 |
| * | add legacy futimes and lutimes functions•••based on patch by sh4rm4. these functions are deprecated; futimens and
utimensat should be used instead in new programs.
