Package: gcc-3.4
Version: 3.4.4-12
Severity: wishlist
Tags: patch

Hi,

Please find attached a patch to add Ada support for gcc-3.4 on 
GNU/kFreeBSD. I haven't forwarded the patch upstream yet, I currently
only have a patch for gcc-3.4 and gcc-4.0, I am working on a patch for
gcc-4.1 as well as for CVS HEAD, then I will send it upstream.

Please also note that the patch also relax the build-dependency on
libc0.1, as we still have our old glibc (with some patches backported 
from version 2.3.5).

Thanks in advance,
Aurelien
