Internal compiler error when trying to cross-compile MIPS

[Parag Patel <parag at cgt dot com>]

Hello.  I'm seeing an internal compiler error in the latest egcs/gcc
when trying to build a MIPS cross-compiler under FreeBSD x86.

Here's the config.status file from my configure command:

    #!/bin/sh
    # This file was generated automatically by configure.  Do not edit.
    # This directory was configured as follows:
    ../egcs/configure --with-gcc-version-trigger=/u/src/gnu/egcs/gcc/version.c --host=i386-unknown-freebsdelf4.0 --target=mips-unknown-elf --with-gnu-as --with-gnu-ld --with-newlib --norecursion 
    # 

The build dies with an internal error when trying to build part of the
libgcc2 library, specifically something to do with the exception
handling code that's built with "_eh" in the Makefile.

I only need the C compiler and not the C++, but making it build just C
instead of using the "cross" target didn't work around this problem.

The output from the crash is attached below as text.  The files x.c,
x.i, and x.s (really just gcc's libgcc2.c) are also attached below as
bzip2-ed source.

Please feel free to contact me for any more details.
