I haven't downloaded any source, or even gcc yet, but I would be
interested in getting some feedback on the difficulty of changing this.
Judging from the behavior, it seems as though pathname expansion uses
its own mechanism to determine if a file matches the wild card, not the
one built into Win32 (FindFirstFile with the wild card name as a
parameter). If it's not difficult to switch to using the OS wild card
matching, then wouldn't this automatically give the correct behavior on a
FAT/NTFS/HPFS partition AND a drive mounted from a Unix box that is
case sensitive? Any ideas?

I don't believe there is a way of doing this. One workaround is to
lowercase all files - I use a perl script that goes:
for $filename ( @ARGV ) {
rename($filename, "\L$filename") or
warn "lower: could not rename '$filename' - $!\n";
}
I realise this may not always be possible - IMO Cygwin should provide an
option, probably as part of mount(1), to ensure that the readdir type
system calls used for wildcarding / filename completion return
lower-cased filenames, when used on a filesystem that is mounted with
the no-mixed option. Of course, all files on that filesystem would then
appear to be lower case to ls etc.
