You forgot to tell on what version of Windows did this happen.  If
it's NT, then the reason is that DJGPP programs cannot access long
file names on NT, and so the pattern rule above doesn't fire because
Make doesn't see a file note.java, only note~1.jav.

If the problem happens on Windows 9X, where long file names *are*
aupported, please invoke Make with the -d switch and examine the
output looking for possible clues.  If you cannot figure that out,
post the entire output here.

Make 3.77 has several sugnificant changes in DOS/Windows support
relative to 3.75.  OTOH, Cygwin's Make 3.75 has some Cygwin-specific
features that were never integrated into the official Make
distribution.  Go figure what that means...

Of course.  These two are equivalent.
