latest snapshot won't bootstrap on mips-sgi-irix5.2

[Alexandre Oliva]

I've got a repeatable bootstrap failure on mips-sgi-irix5.2 with
BOOT_CFLAGS="-O4 -g", configured with haifa scheduler disabled, but
shared libraries enabled.  The problem occurs while building stage2
libgcc.a (i.e., ./xgcc was built with stage1/xgcc).  Here's the actual 
error:

./xgcc -B./ -O2   -DIN_GCC    -W -Wall -O4 -g -I./include   -g1  -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -fexceptions   -I. -I/n/temp1/gcctest/bin/../src/egcs/gcc -I/n/temp1/gcctest/bin/../src/egcs/gcc/config \
  -c -fexceptions /n/temp1/gcctest/bin/../src/egcs/gcc/cp/exception.cc
/n/temp1/gcctest/bin/../src/egcs/gcc/cp/exception.cc:312: Internal compiler error.
/n/temp1/gcctest/bin/../src/egcs/gcc/cp/exception.cc:312: Please submit a full bug report to `egcs-bugs@cygnus.com'.

The stack trace follows:
