04a42d5ee0 Turn off the "-O2 flag TRIGGERS KNOWN OPTIMIZER BUGS" warning.
From current testsuite results, the optimizer bugs don't appear to exist
anymore.  RTH@cygnus.com did a lot of work on the Alpha ELF code generator
for GCC 3.2[.0].  A recent FreeBSD/AXP GCC bootstrap is at
http://gcc.gnu.org/ml/gcc-testresults/2002-09/msg00604.html
In this bootstraps, all gcc libraries are built with -O2 and c-torture
gives -O2 a real workout.  None of the remaining failures have anything
to do with -O2 optimizer bugs.

4396d0e99f cc -O0 and -O1 didn't do the easy optimization of alignment for space.
Instead it attempted to do the easy optimization of alignment for time,
which should be to 1-byte alignment on i386's.

d549989694 Add the `WANT_FORCE_OPTIMIZATION_DOWNGRADE' knob. If set to an integer
value, it forces GCC to not optimize above this level.  For intance, GCC
made with "WANT_FORCE_OPTIMIZATION_DOWNGRADE=1" is a good setting for the
Alpha platform when building ports.

0f79d73473 Support printf format checking of FreeBSD kernel formats %[Dbrz].
This is enabled by the undocumented option -fformat-extensions.
This option should be named better and/or give more control over
the extensions.

Fixed a message - don't warn about the field width when it's the
precision that has the wrong type.  Didn't fix excessive checking
for the precision relative to the type - ANSI requires both to be
ints, but gcc permits the field width to be either int or unsigned
int.

a4cd5630b0 Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the
non-i386, non-unix, and generatable files have been trimmed, but can easily
be added in later if needed.

gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's
handy to have both available for reference for such little cost.

The freebsd-specific changes will then be committed, and once the dust has
settled, the bmakefiles will be committed to use this code.
