I think I understand now, thanks for explaining.

This patch doesn't take care of things in subdirectories or executable
programs, though.  I'm unsure this will help much at all.  For example,
cross-building vandusen from a checkout would probably break due to the
final program not getting recompiled (you could argue that's due to a
broken dependencies list in the Make target, but the problem exists
either way).

Using "make" for eggs seems wrong to me anyway: normally eggs are always
built in full after downloading.  Only very ocasionally does one need to
rebuild just a part.  But during development this might be helpful...

Anyway...  Because I don't know of a way to fundamentally fix it,
I've slightly modified your patch to at least make it handle
subdirectories.  I've added a patch to allow SRE expressions as a test
for find-files, as well (it only accepted procedures, strings and
precompiled irregex objects).  The patch also updates the documentation.

Cheers,
Peter
