It's a LFS/RedHat mix. gcc and make are from source, glibc and binutils
are from RPM.

gcc             : 3.3.3
glibc           : 2.3.2-33.9
make            : GNU Make 3.80
binutils        : 2.13.90.0.20-7

See above.

I'm using a host.def which I've derived from linux.cf.

The only xc/config/cf file that has BuildGLULibrary is sun.cf. I've
followed it and put this in my host.def:

-----------------------------------------------------------------
#ifndef BuildGLULibrary
#define BuildGLULibrary YES
#endif
-----------------------------------------------------------------

FWIW, I defined BuildGLXLibrary and BuildLibraries too, but they have no
notable effect over what I already achieve by defining BuildGLULibrary.

Now it attempts compilation of GLU, but the following error occurs:

-----------------------------------------------------------------
make[5]: Entering directory `/usr/src/build/lib/GLU/libnurbs/internals'
rm -f arc.o
c++ -c -O2         -I/opt/zlib/include  -I/opt/expat/include    -I/opt/
fontconfig/include       -I/us r/src/xc/lib/Xrender       -I/usr/src/xc/
include/extensions        -I/usr/src/xc/extras/freetype2/inc lude  -I/usr/

In file included from arc.h:46, from arc.cc:47: bufpool.h:46:22:
mystdlib.h: No such file or directory
-----------------------------------------------------------------

I had to add this to DefaultGcc2i386Opt: 
-I /usr/src/xc/extras/ogl-sample/main/gfx/lib/glu/libnurbs/nurbtess

Now it gets over that, but fails with the following error:

-----------------------------------------------------------------
make[5]: Entering directory `/usr/src/build/lib/GLU/libnurbs/internals'
rm -f arc.o

bufpool.h: In member function `void Pool::free_buffer(void*)':
bufpool.h:88: error: `assert' undeclared (first use this function)
-----------------------------------------------------------------

At which point I stopped. I don't know what the issue is. bufpool.h
apparently does #include "myassert.h", and there's a -DLIBRARYBUILD in
effect so it should pick up #include <assert.h>. I even tried commenting
out the surrounding test to make sure assert.h is included, and I still
get this error.
