Jon,

Thank you for your reply. I'm not sure exactly what you had in mind
for the debugger. I'm not used to debugging tools like this; so,
here's what I did (if there's something else I could do to
provide more useful information, please provide instructions):
1) I ran make until it was in the infinite loop, 2) I launched
gdb and attached to the make process. Here's what I got (it
means nothing to me, but perhaps means something to someone
else):

(gdb) bt

As far as GNU+Linux: I don't have such a system available and so can't
try it there.


I do have one additional "clue". It appears to be related to the fact
that
I have declared some object files to be ".INTERMEDIATE:". If I remove
this,
then the infinite loop does not occur. The problem with this, though, is
that it always builds those object files, which is not what I want.

Regards,
Kirk
