Mandrake 8.2 on Pentium4 with gcc-3.1
>Description:
While bootstrapping:
/bin/sh ./libtool --mode=compile /home/cwg/install/src/objdir/gcc/xgcc -B/home/cwg/install/src/objdir/gcc/ -B/usr/local/i686-pc-linux-gnu/bin/ -B/usr/local/i686-pc-linux-gnu/lib/ -isystem /usr/local/i686-pc-linux-gnu/include -DHAVE_CONFIG_H -I. -I../../../gcc-3.1/libjava -I./include -I./gcj -I../../../gcc-3.1/libjava -Iinclude -I../../../gcc-3.1/libjava/include -I../../../gcc-3.1/libjava/../boehm-gc/include -DGC_LINUX_THREADS=1 -D_REENTRANT=1 -DTHREAD_LOCAL_ALLOC=1 -DSILENT=1 -DNO_SIGNALS=1 -DNO_EXECUTE_PERMISSION=1 -DALL_INTERIOR_POINTERS=1 -DJAVA_FINALIZATION=1 -DGC_GCJ_SUPPORT=1 -DATOMIC_UNCOLLECTABLE=1 -I../../../gcc-3.1/libjava/libltdl -I../../../gcc-3.1/libjava/libltdl -I../../../gcc-3.1/libjava/.././libjava/../gcc -I../../../gcc-3.1/libjava/../zlib -I../../../gcc-3.1/libjava/../libffi/include -I../libffi/include -D__NO_MATH_INLINES -ffloat-store -W -Wall -march=pentium4 -msse2 -O2 -mfpmath=sse -c -o java/lang/strtod.lo ../../../gcc-3.1/libjava/java/lang/strtod.c

>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.
