[PATCH] Updated glibc-gcc3.patch

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

I finally got to testing updated glibc-gcc3 patch.
The tests I was running are attached too. At the beginning of the Makefile
you can fill any 3 different compilers and it will test all combinations of
throwing exceptions (I used slightly modified Nathan Sidwell's
g++.old-deja/g++.eh/catch12.C, where the throwing/catching C++ code is
either in the main program, or in shared library dlopened from a C stub.
It is throwing through some functions within that C++ code, through a
C function in another dlopened shared library compiled with -fexceptions and
through qsort. Plus there is Mark Kettenis' test_eh.c test with explicit -lc,
since otherwise __frame_state_for is picked up from -lgcc).
I tested this with gcc trunk (patched so that it uses -shared-libgcc by
default only when needed (ie. for C++ and Java)), gcc-2.96-RH (set up as
compatibility compiler, with its libstdc++.so explicitely linked against
-lgcc_s) and egcs (here I just had an egcs1.1.2 libstdc++.so compatibility
library trivially hacked up so that it has __frame_state_for and frame
registry as UND symbols - didn't want to recompile all compat libs).
In case of egcs, I compiled the *3.{tst,so} binaries on RHL 7.2 box and
copied them.
glibc was compiled with trunk gcc (__attribute__((used)) patch was needed
too), plus old gcc-2.96-RH __frame_state_for compatibility patch (not
included here).
