make profiledbootstrap is still broken on (some?) 64bit targets when 
BOOT_CFLAGS="-O2".   We're seeing this on x86_64 and ppc64.  During the third 
stage something goes wrong in the preprocessor:

# for f in $(find ./ -type f -name cpp); do ls -l $f; PATH=$(dirname
$f) $f -dM /dev/null | grep __DBL_MAX__; done
-rwxr-xr-x 1 root root 279196  4. Dez 18:20 ./gcc/cpp
#define __DBL_MAX__ ÃÂ.3200111555710001e+310
-rwxr-xr-x 1 root root 258066  4. Dez 17:47 ./stage1-gcc/cpp
#define __DBL_MAX__ 1.7976931348623157e+308

#define __DBL_MAX__ 1.7976931348623157e+308

This causes the build to fail like so:

I understand that this may not be a showstopper, but I wanted to be sure you're 
aware of it.  This is PR #33992, which is still unconfirmed.  I think this is 
because it was originally filed using a Gentoo GCC, but we've since confirmed it 
with several vanilla 4.3 snapshots.
