	This patch causes bootstrap failures on powerpc-aix,
sparc-solaris, powerpc-darwin, and appparently all big-endian targets.
The failure is a SEGV at the first use of stage 2 cc1 compiling conftest.c
during libgcc configure:

...
checking for suffix of object files...

int
main ()
{

  ;
  return 0;
}

configure: error: cannot compute suffix of object files: cannot compile


Program received signal SIGSEGV, Segmentation fault.
0x002cf780 in reload_combine_note_store (dst=0xff0b90e0, set=<value optimized out>, data=0x0)
    at ../../egcc-SVN20070909/gcc/postreload.c:1018
1018              reg_state[i].store_ruid = reload_combine_ruid;

Recompiling postreload.c without optimization allows the test to proceed.

David
