AC_EXEEXT macro problem

[Guido van Rossum]

I'm the creator of Python.  I'm new to this list.  We use autoconf
(happily, I might add) and I've run into a snag.  Please look at this
Python bug report on SourceForge:

  http://sf.net/tracker/?group_id=5470&atid=105470&func=detail&aid=420416

It appears that the AC_EXEEXT macro is naive, and fails on BeOS.  Can
someone help me fix the macro?  (It would seem *.xSYM needs to be
added to its case statement of ignored extensions.)
