	This is a good start, but I would prefer to accept a real fix
instead of an interim kludge.  BTW, have you filled out an FSF assignment
form?

	collect2 already handles all of the XCOFF issues and extracts
symbols names for you to examine, you only need to understand collect2.
collect2 already is suppose to export "_GLOBAL_" and "GLOBAL_." symbols,
so I am not sure what additional purpose your "make_aix_exp" utility
performs.  If collect2 is missing some symbols of that form, collect2
needs to be fixed.  If you perform any necessary additional examination
inside collect2, you do not need a second export file which I oppose.

	Also, I would like to make any necessary changes to the export
list to support exception handling symbols at the same time.
