When I attempt to compile gcc 4.5 on a sparc machine under Debian Linux 5.0 I
get the following error:

/home/mrichmon/gcc-4.5-20090402/gcc/genattrtab.c: In function âattr_rtxâ:

Happens on sparc-sun-solaris2.11 as well, so this seems to be a generic sparc
issue.  Have you investigated further yet?  Otherwise, I can start a reghunt to
find the culprit patch.

Ok, thanks.  The question was addressed more to Laurent, who had taken on
the bug.
