>Description:
Running some programs that were compiled using glibc 2.0 libraries
doesn't work. I get the following error:

rincewind:/usr/src/lib/glibc-2.0.111$ /usr/src/devel/jdk1.2v/build/linux/bin/java
/usr/src/devel/jdk1.2v/build/linux/bin/m68k/native_threads/java: error
in loading shared libraries:
/usr/src/devel/jdk1.2v/build/linux/lib/m68k/classic/libjvm.so:
undefined symbol: __divdi3

The version of GLIBC it was compiled with: glibc-2.0.7-29.m68k.rpm
(RedHat 5.2 distribution)

I have used nm to find the symbol, it is defined in the 2.0 version
as:

0006ff94 T __divdi3

and in the 2.1.111 version as:

000a0eb0 t __divdi3

If I'm not mistaken, it really comes from libgcc.a. Why was it not
resolved at link time from libgcc.a? Or rather, why is __divdi3 in the
2.0 version of glibc?

>How-To-Repeat:
Run a program compiled with glibc 2.0 that uses __divdi3 on a 2.1 system.
>Fix:
Dump the symbol as a global from glibc 2.0, or include it in glibc 2.1
as global.
