The globbing is not where the confusion lies. This globbing:
$ ls xwin*
ls: cannot access xwin*: No such file or directory
works as expected and did not confuse anybody. Here's what confused
the OP:
$ ls xwin
xwin
$ ls xwIN
xwIN
This is unquestionably a normal, Cygwin specific condition, caused
by the semantics of the underlying NTFS, but very confusing to
someone whose experience is with UNIX.
This note:
http://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-casesensitive
warns that you cannot have two filenames in the same directory that
differ only by case, because of NTFS semantics.
It could be improved to warn that because of NTFS semantics there
are also filenames which exist but which Cygwin's readdir() does not
return, and which therefore are truly hidden -- will never show up
in directory listings or globs.
I think this is what the OP was volunteering to do.
Cheers,
MetaEd
