* wait.h: add linux specific, thread-related waitpid() flagsrofl0r2013-01-041-0/+4
| | | | | | | | | these flags are needed in order to be able to handle lwp id's which the kernel returns after clone() calls for new threads via ptrace(PTRACE_GETEVENTMSG). fortunately, they're the same for all archs and in the reserved namespace.
* fix issues with wait constants in stdlib.hRich Felker2012-10-211-2/+0
| | | | | | the W* namespace is not reserved, so the nonstandard ones must be moved under extension features. also WNOHANG and WUNTRACED were missing.
* default features: make musl usable without feature test macrosRich Felker2012-09-071-0/+2
| | | | | | | | | | the old behavior of exposing nothing except plain ISO C can be obtained by defining __STRICT_ANSI__ or using a compiler option (such as -std=c99) that predefines it. the new default featureset is POSIX with XSI plus _BSD_SOURCE. any explicit feature test macros will inhibit the default. installation docs have also been updated to reflect this change.
* support _BSD_SOURCE feature test macroRich Felker2012-05-221-1/+1
| | | | | patch by Isaac Dunham. matched closely (maybe not exact) to glibc's idea of what _BSD_SOURCE should make visible.
* move wait.h macros out of bits. they do not vary.Rich Felker2011-04-211-2/+22
