>Description:
        multimedia/xvidcore in src/xvid.c xvid_gbl_info()
        expects to be able to reference _SC_NPROCESSORS_CONF
        which seems to not exist on NetBSD 4.0

        That symbol is in <unistd.h> in current and NetBSD 5 (BETA)
        but is not prseent in NetBSD 4.

>How-To-Repeat:
        Attempt to build multimedia/xvidcore on a NetBSD 4 system.

        I use pkg_comp with libkver and NetBSD 4.0 release sets
        installed (not the x* sets, instead pkgsrc modular xorg
        for this build, but that's not relevant here).

../../src/xvid.c: In function 'xvid_gbl_info':
../../src/xvid.c:682: error: '_SC_NPROCESSORS_CONF' undeclared (first use in 
this function)
../../src/xvid.c:682: error: (Each undeclared identifier is reported only once
../../src/xvid.c:682: error: for each function it appears in.)
*** Error code 1

Stop.
make: stopped in 
/pkg_comp/obj/pkgsrc/multimedia/xvidcore/4x/xvidcore/build/generic

        before that error there are a whold bunch of redefined type
        warnings which should probably also get fixed ...

>Fix:
        For the reaal problem, find a way to avoid using _SC_NPROCESSORS_CONF
        on NetBSD 4.0.

        For the redefinitions, have portab.h not define stuff that
        isn't needed...
