A note here is that MariaDB / MySQL builds fine with gcc 3.4.3 on our
OpenSolaris machine.  I am sure that c++ templates was supported even
for gcc 2.95.2 as we have used c++ templates (for lists) in the code
since 1995, way before gcc 3.x.

There may be another reason for using gcc 4.3 on Gentoo, but it can't
be because of c++ templates.

This bug report doesn't give any indication of why gcc 4.3 would be
required;  It's only about marking the packet to require gcc 4.3
for building.

The real bug seams to be:

./include/sync0rw.h:425:2: #error HAVE_ATOMIC_BUILTINS is not defined. Do you
use enough new GCC or compatibles?      

Looks like a bug in the MySQL code. This code has however changed
since then, so it may not be an issue anymore.
(After all, we do build now with gcc 3.4.3)

Thanks.
