Re: ix86_data_alignment: bad defaults?

What if the object format doesn't allow recording alignments that
high?  For example, DJGPP's coff format can only record alignments up
to 2**4 (16) bytes, but 256 bits is 2**5 (32) bytes.


So BIGGEST_ALIGNMENT > MAX_OFILE_ALIGNMENT.  That's a logical
contradiction.  Bummer.

min (256, MAX_OFILE_ALIGNMENT)?

For ELF, this would be 256, good. For pecoff, that would be smaller.
