Right now, all _POSIX_SOURCE seems to do is exclude a number of constants and functions from being defined, supposedly because they aren't part of the POSIX standard. Now, newlib != glibc, but the examples I mentioned before could be compared to their glib counterparts (see below regarding <sys/select.h>). > So, that would imply that "we" really should actively fix up the headers > to make sure that it is properly handled. OK, but I think these are uncommon cases; I've built a *LOT* of packages of all types, and this has not generally been a problem. > I was hoping for concrete examples. Do you have any? gmime2: gmime-gpg-context.c: In function `gpg_ctx_op_step': gmime-gpg-context.c:1089: error: `fd_set' undeclared (first use in this function) gmime-gpg-context.c:1089: error: (Each undeclared identifier is reported only once gmime-gpg-context.c:1089: error: for each function it appears in.) gmime-gpg-context.c:1089: error: parse error before "rdset" gmime-gpg-context.c:1096: error: `rdset' undeclared (first use in this function) gmime-gpg-context.c:1114: error: `wrset' undeclared (first use in this function) gmime-gpg-context.c:1124: error: `wrsetp' undeclared (first use in this function) fd_set is defined in <sys/types.h> (which is also called by <sys/select.h>, but only if !defined(_POSIX_SOURCE)), but with this condition: /* We don't define fd_set and friends if we are compiling POSIX source, or if we have included (or may include as indicated by __USE_W32_SOCKETS) the W32api winsock[2].h header which defines Windows versions of them.

Since _POSIX_SOURCE on Cygwin doesn't add anything, I can't remember a case that I've had to *add* such a define.
