Attached are the two files to solve the __udivdi3, version GLIBC_2.0 no
symbol errors ...


Put the divdi3.c to glibc-2.2.5/sysdeps/wordsize-32/divdi3.c, and Makefile
to glibc-2.2.5/sysdeps/i386/Makefile


If you can't get these attachment, you can try downloading from ...

[divdi3.c]
http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/sysdeps/wordsize-32/divdi3.c

[Makefile]
http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/sysdeps/i386/?cvsroot=glibc


After replacing these files, recompile glibc-2.2.5 again.

If you don't apply these patches, you won't be able to run X11 programs
such as mozilla or vmware (__udivdi3 undefined).

If you download divdi3.c from the cvs site, make sure you commented out
the following like below, else the code will fail to compile with the
stock glibc-2.2.5 source.

	//INTDEF(__divdi3)


All files compiled with the new gcc3.2 and recompiled glibc-2.2.5 will
save you some space after you strip them. Seems to be more efficient.

Thanks,
Jeff
