Bug#353346: gcj can't make shared libs on hppa. (followup)

[Joel Soete]

Hello Matthias,

Personaly I don't care of gcj but well glibc and according to jda's mail 
<http://gcc.gnu.org/ml/gcc-patches/2006-03/msg00815.html> this patch 
would fix the mentioned pb for all gcc 4.x

This is well comitted upstream, I check with some script like:
svn diff --old http://gcc.gnu.org/svn/gcc/tags/gcc_4_0_3_release \
        --new http://gcc.gnu.org/svn/gcc/branches/gcc-4_0-branch \
       >  Gcc-4.0-br.diff-$(date +'%Y%m%d')

but I didn't find yet integrated neither in gcc-4.1 nor gcc-4.0 debian pkg?

I so tested the attached patch with gcc-4.0 (afaik the default build 
tool for glibc6) and it makes well its job ;-)

Thanks in advance,
   Joel
