BTW, Python-CVS can't be compiled FreeBSD-CURRENT, nowadays.
Because FreeBSD-CURRENT hides non-POSIX stuffs on _POSIX_C_SOURCE mode,
Modules/posixmodule.c fails to find chroot, minor, major, makedev and etc.
This patch enables python builds on FreeBSD-CURRENT but I can't
find another generous workaround.
