Ok, I've addressed all of the review comments, including the results of
the four ***QQQ***estions.  Quick-N-Dirty spot testing on native cygwin,
native mingw, cygwin->mingw, linux->mingw, linux->cygwin all look good,
so I'm about to rebase on my private branch.  However, to make that a
little less painful I'm going to squash all my changes that arose from
this review into a single commit first (no sense in working four times
as hard to fixup four separate commits).

Here are the log messages for the new three commits. Obviously, after
the squash, the resulting log message will look a lot like the one for
the patch as originally posted in this thread, but with a lot of the
function names changed.

This is just an FYI.  The take-away here is that I did go ahead and
rename all the functions to
  func_convert_{file|path}_X_to_Y
and moved them to just before func_mode_compile.  I changed all comments
and function names to use the 'file' (or file name) and 'path'
terminology, instead of the original 'path' and 'pathlist' terminology.

Peter is going to hate me.
