2012-05-13remove some no-op end of string tests from regex parser•••these are cruft from the original code which used an explicit string length rather than null termination. i blindly converted all the checks to null terminator checks, without noticing that in several cases, the subsequent switch statement would automatically handle the null byte correctly. Rich Felker1-4/+0
2012-05-13another BRE fix: in ^*, * is literal•••i don't understand why this has to be conditional on being in BRE mode, but enabling this code unconditionally breaks a huge number of ERE test cases. Rich Felker1-0/+2
2012-05-13let sysconf accurately report # of cpus available•••i've been trying out openmp and it seems like it won't be much use without this... Rich Felker1-2/+10
2012-05-12use __h_errno_location for h_errno•••we do not bother making h_errno thread-local since the only interfaces that use it are inherently non-thread-safe. but still use the potentially-thread-local ABI to access it just to avoid lock-in. Rich Felker3-1/+14
