Ian,
Thanks. On x86_64-apple-darwin10 with...
configure flags: --prefix=/sw --prefix=/sw/lib/gcc4.6 --mandir=/sw/share/man --infodir=/sw/lib/gcc4.6/info --with-build-config=bootstrap-lto --enable-stage1-languages=c,lto --enable-languages=c,c++,fortran,lto,objc,obj-c++,java --enable-build-with-cxx --with-gmp=/sw --with-libiconv-prefix=/sw --with-ppl=/sw --with-cloog=/sw --with-mpc=/sw --with-system-zlib --x-includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib --program-suffix=-fsf-4.6 --enable-checking=yes --enable-cloog-backend=isl
and...
make -j profiledbootstrap BOOT_CFLAGS="-g -O3" CFLAGS_FOR_TARGET="-g -O3"
there are no regressions. Nice.
