While it was brought in r258179 only to fix a build issue,
bringing the rest of the change has the advantage of fixing

3b5bdcdf37 gcc: Backport fixes for -W parentheses in C++
This fixes GCC 19564:

  http://gcc.gnu.org/ml/gcc-patches/2007-01/msg00545.html

The patch and its fixes are used by Google in their enhanced gcc-4.2.1
port and predates the license switch in GCC so they are still under
GPLv2.

9636f78ba3 GCC: bring back experimental support for amdfam10/barcelona CPUs.
Initial support for the AMD amdfam10 chipsets has been available in the
gcc43 branch under GPLv2. AMD and some linux distributions (OpenSUSE) did
a backport of the amdfam10 support and made it available.

This is a revised subset of the support initially brought in in r236962
and later reverted. The collateral efects seem to have disappeared but
it is still recommended to set the CPUTYPE with caution.

fcd6d20340 Update the gcc43 changelog.
The issue solved in r250392 actually originated upstream and was
fixed in upstream gcc43 branch in 2006/10/24 (under GPLv2).

Register it in the appropriate ChangeLog for reference.

5917560e17 Bring a couple of fixes for gcc optimizations.
The GCC4.3 branch contains some optimization fixes
that were not considered regressions and therefore
were never backported. We are bringing a couple of
them that are under GPLv2 since they were made
before the license switch upstream.

While here, add the GCC revision numbers in the
log.

a6c34d9e26 Revert r236962 - Experimental amdfam10/barcelona support.
The patches are unexpectedly causing gcc to fail while
building ports/graphics/ImageMagick even when the cpu
flags are not used.

b28518a59a Add experimental support for amdfam10/barcelona from the GCC 4.3 branch.
Initial support for the AMD barcelona chipsets has been available in the
gcc43 branch under GPLv2 but was not included when the Core 2 support
was brought to the system gcc.

AMD and some linux distributions (OpenSUSE) did a backport of the amdfam10
support and made them available. Unfortunately this is still experimental
and while it can improve performance, enabling the CPUTYPE may break some
C++ ports (like clang).

Special care was taken to make sure that the patches predate the GPLv3
switch upstream.
