Problems compiling hugs-2003.11 with threading and hopengl support

   so I repeat it here... ]

If I read the bug entry on gentoo.org correctly, you
build Hugs with --enable-hopengl and --with-pthreads.
I haven't tried this combination yet, but AFAIK there
are issues with dlopen()ing the NVIDIA OpenGL lib
multiple times (which Hugs does IIRC) when pthreads
are used and you don't have the latest and greatest
libc and dynamic loader. I'm not sure if Hugs can
easily be changed to dlopen() every lib only once, so
I propose to drop the --with-pthreads option until
NVIDIA and glibc are in sync again...   :-(

Cheers,
