While bootstrapping:

>How-To-Repeat:
$ mkdir objdir
$ cd objdir
$ ../gcc-3.1/configure --enable-threads --with-cpu=pentium4 --enable-version-specific-runtime-libs
$ make -j 2 CFLAGS='-march=pentium4 -msse2 -O2 -mfpmath=sse' LIBCFLAGS='-march=pentium4 -msse2 -g -O2 -mfpmath=sse' LIBCXXFLAGS='-march=pentium4 -msse2 -g -O2 -mfpmath=sse -fno-implicit-templates' bootstrap-lean
>Fix:
Work around: not using -march=pentium4 -msse2 -mfpmath=sse as compilation options.
