From the implemtation of a GIF87a reader that I wrote, and upgraded
to GIF89a there isn't really any difference.  The biggest difference
is that they have used some of the extention blocks to actually
do things.  So the simple answer to this problem is make a tiny
patch to the PBM software to recognize GIF89a as a magic number in the
header.

[for the reason this is a post rather than a mail message]

Now, if you happen to have a GIF file that does contain the new
extention blocks that are mentioned in the 89 spec.  I'm interested
in getting a copy so that I can check the code that I have written
to decode these extension blocks.
