Tru64 Unix 5.0 on a DEC XP1000 Workstation
>Description:
gcc 3.0 fails to bootstrap. It halts in stage 2 when running 
"configure" for libstdc++-v3. Here are the last few lines 
from config.log found in $(OBJ)/alphaev6-dec-osf5.0/libstdc++-v3:

configure:2597: /tmp_mnt/auto.all/data0/tobi/obj/gcc/xgcc -B/tmp_mnt/auto.all/data0/tobi/obj/gcc/ -nost

configure: failed program was:
#line 2586 "configure"
#include "confdefs.h"

int main() {

  #if __GNUC__ < 3
    not_ok
  #endif
  
; return 0; }

I verified that xgcc really crashes when trying to 
compile this source with these options.

I bootstrapped gcc using DEC CC V6.1-011. I first tried 
to bootstrap using gcc 2.95.1, but that gave me an internal
compiler error in gcc 2.95.1 even in stage zero.
