Hmm, with "#define _XOPEN_SOURCE 500" I get these (new) errors:

./posixmodule.c: In function `posix_tmpnam':
./posixmodule.c:3494: warning: assignment makes pointer from integer without a cast

./signalmodule.c:83: `SIGMAX' undeclared here (not in a function)
./signalmodule.c:83: size of array `Handlers' has non-integer type

Both errors can only be fixed using __USE_MISC:

   __USE_MISC           Define things common to BSD and System V Unix.

It is defined when either _BSD_SOURCE or _SVID_SOURCE is
defined... question is: which to use ?
