 It's interesting to note that profiledbootstrap break amd64 build too, though
for different reason:

../../gcc-current/gcc/c-parser.c:4672:19: error: 'incr' may be used
uninitialized in this function [-Werror=uninitialized]
cc1: all warnings being treated as errors

  For amd64 I configured with these settings:

../gcc-current/configure --prefix=/home/artem/testing/gcc46 --enable-shared
--enable-bootstrap --enable-languages=c,c++ --enable-threads=posix
--enable-checking=release --with-system-zlib --disable-libunwind-exceptions
--enable-__cxa_atexit --enable-libssp --with-gnu-ld --with-lto --disable-nls
--verbose --with-arch=athlon64 --target=x86_64-slackware-linux
--build=x86_64-slackware-linux --host=x86_64-slackware-linux --disable-multilib
--enable-checking=release

  Doing normal (not profiled) build with these settings succeeds for me.
