Perhaps, but I found it in some code that I'm porting to GAS from
a different assembler. It looks like I can get the desired effect
in GAS with .align pseudos, something like this:

  .balign 16
  foo=.
  # stuff deleted from reduced test case, less than 16 bytes
  .balign 16
  foo=.
  # more stuff

I added a declaration for frag_count to your patch and it successfully
issues an error on this code (and also on the original source from which
this code was simplified).

Thanks,

Dan
