I built gcc 1.37.1 as a cross compiler on a vax running Ultrix 3.1.  The
links are:

	aux-output.c --> ../config/out-ns32k.c
	config.h --> ../config/xm-vax.h
	md --> ../config/ns32k.md
	tm.h --> ../config/tm-pc532.h

[I'm trying to get it to generate code for a 32532 based personal
computer; since I don't have the machine built yet, much less have an
operating system for it, I'm trying to run gcc as a cross compiler.]

When I ask gcc to compile __cmpsf2 in gnulib.c, it dies with an illegal
instruction.

The file tm-pc532.h is the 2 lines --

#define TARGET_DEFAULT 1
#include "tm-ns32k.h"

plus a redefinition of STANDARD_EXEC_PREFIX and
STANDARD_STARTFILE_PREFIX to point to a subdirectory of my home
directory and *NOTHING* else.

The output of running

	./gcc -O -B./ -I. -I.. -I../config -c -DL_cmpsf2 ../gnulib.c -S -v 

is:

gcc version 1.37.1
 ./cpp -v -DL_cmpsf2 -I. -I.. -I../config -undef -D__GNUC__ -Dns32000 -Dunix -D__ns32000__ -D__unix__ -D__OPTIMIZE__ ../gnulib.c /usr/tmp/cca08339.cpp
GNU CPP version 1.37.1
 ./cc1 /usr/tmp/cca08339.cpp -quiet -dumpbase ../gnulib.c -O -version -o gnulib.s
GNU C version 1.37.1 (32000, National syntax) compiled by CC.
default target switches: -m32081
./gcc: Program cc1 got fatal signal 4.

If I remove the `-O', it compiles okay.

p.s. yes, I realize that it seems a little silly to compile gnulib.c
with gcc, but it really isn't -- I want to know which ones generate
function calls and which ones get open coded.  The ones that generate
function calls, I'm going to need assembly language versions of.  And I
want to know which ones those are.
