m68k assembler errors

["Beere, Chris" <Chris dot Beere at cwcom dot co dot uk>]

Hello,
         
         We are currently using gcc 2.4.5 and have decided to upgrade to
2.95.2. Our system is an old version of Unix, System V R3V8 from Motorola,
on their Delta platform which uses the M68040 processor. We are  having some
trouble getting the assembler parts to assemble correctly. I decided it
would be better to use the GNU assembler and linker so I changed the
compiler configuration file /lib/.compilerc to reflect this.
Current assembler and linker
/bin/as
/bin/ld

(hilda)# /bin/as -V
/bin/as: assembler - @(#)pass0.c        55.1     91/05/29     
Nonexistent file
(hilda)# /bin/ld -V
ld : SYSTEM V/68 R3V7, Motorola C Issue 03.70 (91/07/26) : Version 1.8.2.1:
11/19/85
(hilda)# 

The GNU assembler and linker are:-
/usr/local/bin/gas
/usr/local/bin/gld

/usr/local/bin/gas --version
GNU assembler 2.9.1

When we run 'make bootstrap' it fails to assemble the floating point
instructions:-

rm -f tmplibgcc1.a

  rm -f ${name}.o; \

make[2]: *** [libgcc1.a] Error 1

make[1]: Leaving directory `/users2/gnu/gcc/obj/gcc'
make: *** [bootstrap] Error 2 

So I added -m68040 option into the file /lib/.compilerc and did the make
again,  failed at same point with the first error only.
Error: Unknown operator -- statement `fdmov.d 8(%fp),%fp0' ignored  

How do we make gas work properly with 68040 instructions? The old assembler
works.
