Re: work for glibc 2.2.5-14
Daniel,
Ok. I re-read you message and follow it now. The problem
with using the versioning fixup if it doesn't go into
gcc 3.2 is that the sister patch required for glibc is unlikely
to go into glibc-2-2-branch either so we will have to add
both in by hand. I'm not sure what happens if you use the
first generation patch for libgcc-compat with Franz's gcc 3.2
version symbol fixup. I haven't really tried that one yet.
As I said, I never have seen any breakage under a gcc 3.1.1
built glibc with the first generation libgcc-compat patch so
I'm not too worried either way.
Jack
ps The new version of the libgcc-compat patch is attached.
Note the new libgcc-compat will require the next binutils
post 2.13.90.0.3 which resolves a bug in binutils this patch
tickles.
