Mainline doesn't bootstrap on i686-linux

[Andreas Jaeger]

While running make bootstrap on i686-linux with the current version
(updated 18th February 19:00 UTC) I get the following:

./xgcc -B./ -B/opt/gcc-2.97.test/i686-pc-linux-gnu/bin/ -isystem /opt/gcc-2.97.test/i686-pc-linux-gnu/include -O2   -DIN_GCC    -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -isystem ./include  -fPIC -g1 -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED  -I. -I. -I/cvs/gcc/gcc -I/cvs/gcc/gcc/. -I/cvs/gcc/gcc/config -I/cvs/gcc/gcc/../include  -fexceptions -DL_eh -c /cvs/gcc/gcc/libgcc2.c -o libgcc/./_eh.o

Please submit a full bug report, with preprocessed source if appropriate.
See <URL: http://www.gnu.org/software/gcc/bugs.html > for instructions.

I run configure as:
/cvs/gcc/configure --prefix=/opt/gcc-2.97.test --enable-shared \
         --enable-threads=posix \
         --with-gnu-as --with-gnu-ld --disable-nls --with-system-zlib \
         --enable-languages=c,objc,c++,f77

My system: i686-linux, SuSE 7.1, recent binutils, glibc 2.2, Linux 2.4.2pre3

I can send preprocessed files if you can't reproduce it but I expect
that it's easy to reproduce.
