work around a GCC 4.2 bug.

	typeof(1.0fi) != float _Complex
	typeof((float _Complex)1.0fi) != float _Complex
	typeof((float _Complex)1.0i) == float _Complex

In other words: if casting to an equal size, GCC seems to take a
shortcut. By casting down from a double to a float, GCC doesn't take
this shortcut, yielding the proper type.

Obtained from: FreeBSD

add feature_present(3) to test for kernel features.

Modify resolver to handle _ which is not up to spec, but many other operating systems use them now :(

Wow, I'm forgetful today.  Add the actual spawn.h file for posix_spawn(3).

Switch over to uint32_t, the preferred type.

Remove FreeBSD_version definition completely.

Merge changes.

Note quite there yet, but let's save my work :)

Minimize the diff

sys/posix4 doesn't exist anymore.  Setup for new world order.  This does not work entirely but it will soon.

$MidnightBSD$

Add MidnightBSD_version.  Until we correct newvers.sh, this will report the FreeBSD value.  We must first remove all references to FreeBSD_version (OSRELDATE) from mports and the src tree before we can whack this.

__restrict

Oops.. someone forgot to add the definition for strtonum
