2014-03-11move struct semid_ds to from shared sys/sem.h to bitsRich Felker1-16/+1
the definition was found to be incorrect at least for powerpc, and fixing this cleanly requires making the definition arch-specific. this will allow cleaning up the definition for other archs to make it more specific, and reversing some of the ugliness (time_t hacks) introduced with the x32 port. this first commit simply copies the existing definition to each arch without any changes. this is intentional, to make it easier to review changes made on a per-arch basis.
2014-02-22sys/sem.h: cheat and make all longs use time_t insteadrofl0r1-8/+8
most of the members should be time_t anyway, and time_t has the correct semantics for "syscall_long", so it works on all archs, even x32.
2013-06-28work around wrong kernel type for sem_nsems member of struct semid_dsRich Felker1-1/+9
rejecting invalid values for n is fine even in the case where a new sem will not be created, since the kernel does its range checks on n even in this case as well. by default, the kernel will bound the limit well below USHRT_MAX anyway, but it's presumably possible that an administrator could override this limit and break things.
2012-09-07default features: make musl usable without feature test macrosRich Felker1-0/+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.
