The used standard is defined by_POSIX_SOURCE, _POSIX_C_SOURCE, _ANSI_SOURCE and _C99_SOURCE. In that order (sys/cdefs.h). These set the internal defines __POSIX_VISIBLE, __XSI_VISIBLE, __BSD_VISIBLE, __ISO_C_VISIBLE according to the given standard. If nothing is given=20 then #define __POSIX_VISIBLE 200112 #define __XSI_VISIBLE 600 #define __BSD_VISIBLE 1 #define __ISO_C_VISIBLE 1999 is set.

I'm still not convinced that FreeBSD's behaviour is a bug. IMO it's only strict. If you define a standard you get, if not you get all. Although I'm quite sure the FreeBSD community doesn't like it I'll make a patch against sys/defs.h to put a define _BSD_SOURCE at the top of the chain which sets the default environment and post it to the freebsd-current discussion list. > Still, you add a case with "FreeBSD", and "rest of the world", the I'm quite sure it's an object to be extended..
