Trouble building egcs-970922 in i686-linux

[Fred Richardson <frichard at bbn dot com>]

Hi-

I've come across the following error while compiling.  I ran
1997-09-17/gcc/cc1 in gdb and found the problem occurred in
"jmp_uses_reg_or_mem".  Here's a dump from my gdb session.  First I
ran:
    ./xgcc -save-temps -v -B./ -O2   -DIN_GCC   -DUSE_GNULIBC_1 -g -I./include  -fPIC -g1 -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -I. -I. -I./config -c -DL_bb ./libgcc2.c -o _bb.o

to create the temporary files:

    (gdb) r libgcc2.i -v -dumpbase libgcc2.c -g -g1 -O2 -version -fPIC -o libgcc2.s
    The program being debugged has been started already.
    Start it from the beginning? (y or n) y
