Allow WEXITSTATUS etc be defined elsewhere. * stdlib/stdlib.h [__USE_XOPEN]: Define WEXITSTATUS etc. * sysdeps/generic/bits/waitflags.h: Allow including from stdlib.h. * sysdeps/unix/bsd/bits/waitflags.h: Likewise. * sysdeps/unix/sysv/linux/bits/waitflags.h: Likewise. * sysdeps/unix/sysv/sysv4/bits/waitflags.h: Likewise. * sysdeps/generic/bits/waitstatus.h: Likewise.
