[Gnome-print] gnome-print fixes for MacOS X / Darwin

[Dan Winship <danw ximian com>]

Can I commit?

Oops, the ChangeLog entry for gf-pfb.c didn't end up in the diff. It's
basically just that we're moving the <sys/types.h> include to before
the <sys/mman.h> one, because Darwin's sys/ headers aren't very
robust.

The PCL stuff is because ANSI doesn't define what happens when you
define the same symbol non-statically in multiple source files.
