config/i386/linux64.h is not fixed for multilibs yet and therefore
building the 32-bit routines fails on x86-64 with:

./xgcc -B./ -B/usr/x86_64-unknown-linux-gnu/bin/ -isystem /usr/x86_64-unknown-linux-gnu/include -isystem /usr/x86_64-unknown-linux-gnu/sys-include -O2  -DIN_GCC    -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -isystem ./include  -fPIC -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED  -I. -I. -I/abuild/aj/gcc/gcc -I/abuild/aj/gcc/gcc/. -I/abuild/aj/gcc/gcc/config -I/abuild/aj/gcc/gcc/../include -m32 -fexceptions -c /abuild/aj/gcc/gcc/unwind-dw2.c -o libgcc/32/unwind-dw2.o
/abuild/aj/gcc/gcc/unwind-dw2.c: In function `uw_frame_state_for':
/abuild/aj/gcc/gcc/unwind-dw2.c:910: structure has no member named `rsp'
[...]

I hope that we get linux64.h fixed soon so that this works,

Andreas
