2013-03-06fix epoll structure alignment on non-x86_64 archsRich Felker1-1/+5
this fix is far from ideal and breaks the rule of not using arch-specific #ifdefs, but for now we just need a solution to the existing breakage. the underlying problem is that the kernel folks made a very stupid decision to make misalignment of this struct part of the kernel API/ABI for x86_64, in order to avoid writing a few extra lines of code to handle both 32- and 64-bit userspace on 64-bit kernels. I had just added the packed attribute unconditionally thinking it was harmless on 32-bit archs, but non-x86 32-bit archs have 8-byte alignment on 64-bit types.

2013-03-04fix types for wctype_t and wctrans_tRich Felker7-16/+16
wctype_t was incorrectly "int" rather than "long" on x86_64. not only is this an ABI incompatibility; it's also a major design flaw if we ever wanted wctype_t to be implemented as a pointer, which would be necessary if locales support custom character classes, since int is too small to store a converted pointer. this commit fixes wctype_t to be unsigned long on all archs, matching the LSB ABI; this change does not matter for C code, but for C++ it affects mangling. the same issue applied to wctrans_t. glibc/LSB defines this type as const __int32_t *, but since no such definition is visible, I've just expanded the definition, int, everywhere. it would be nice if these types (which don't vary by arch) could be in wctype.h, but the OB XSI requirement in POSIX that wchar.h expose some types and functions from wctype.h precludes doing so. glibc works around this with some hideous hacks, but trying to duplicate that would go against the intent of musl's headers.

2013-02-26fix wrong float_t on x86_64Rich Felker1-1/+1
x86_64 does not have excess precision, at all

2013-02-26fix integer type issue in strverscmpRich Felker1-1/+3
lenl-lenr is not a valid expression for a signed int return value from strverscmp, since after implicit conversion from size_t to int this difference could have the wrong sign or might even be zero. using the difference for char values works since they're bounded well within the range of differences representable by int, but it does not work for size_t values.
