bug when compiling libc2.2.5 + linuxthreads with -Os with a gcc 3.2 crosscompiler

[Hans-Christian Armingeon]

Dear Hackers,

I got this message below. I read http://www.gnu.org/software/gcc/bugs.html , and I decided, that it would be much easier to reproduce this bug, if you take my script, and let it run.
I you need some other things [the things described in http://www.gnu.org/software/gcc/bugs.html ], then mail me. Please no rtfms, I'm a beginner.

The build is ok, when I build with -O2 . Well, I know that playing with -O is dangerous with libc.

I applied this patch to gcc 3.2 and libc 2.2.5

> strong_alias (__old_sys_nerr, _old_sys_nerr);

##End of patch

There are three more patches appended, these patches are needed by the build script. Additional information about the build script is at http://www.kegel.com/xgcc3/ .

Many thanks in advance,
