Follow-up Comment #5:

Sorry, I missed the attached makefile.

This bug is now solved (commit 5667376).  It was caused by a change in
string_glob: in 3.81 it tested whether each file name returned by 'glob'
actually existed, and discarded non-existent ones.  Make 3.82 no longer does
that, and this exposed a bug in MS-Windows 'stat' which assigns no special
meaning to a file name that ends in "/."; it normalizes it, which removes the
period and the slash, and returns information about a file without making sure
it is a directory.

I solved this by using the local_stat wrapper on MS-Windows, which we arrange
to be called from 'glob'.  It now detects this special case and verifies that
the parent directory exists and is a directory.  We just need to remember
never to remove the GLOB_ALTDIRFUNC flag from the call to 'glob' ;-)
