Thanks.

  Matter of taste, I suppose.
  
I didn't realise the deleted .s file problem.  I always do

  (cd mpn; m4 file.asm)>x.s && gcc -g x.s ...

when I debug, since that effetively zeros turnaround time.

Perhaps we should stop deleting the .s file?

  I generally do that with the assembler itself.  E.g.
  
  	call	1f
  	.subsection 2
  1:	mov	(%esp), %ebx
  	ret
  	.previous
  	addl	$_GLOBAL_OFFSET_POINTER_, %ebx
  
Lucky you to have a powerful assembler all the time...

I actually really like m4.  It is tiny yet really powerful, being Turing
complete.  A friend of mine implemented a bignum library in m4, inspired
by GMP's m4 usage, I think.  Convinced of m4's greatness now?  :-)
