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

Hi Joel,
the patch is already applied in gcc-4.1 and gcj-4.1. Fixed in today's
gcc-4.0 upload as well. I think we shouldn't care too much about
gcj-4.0 at this point (will build and upload when time permits it).
