I know from the experience of my mingw32-sup package that cmd.exe and
commmand.com do globbing, it is not as robust though.  For example:
`ls' doesn't do any globbing, it only reports on a list of files given
it on stdin.  I ported it to native win32 using mingw32.

Gnu-win32 reglobs in the startup of the program (none of the programs
were modified to do the globbing) in order to emulate the UNIX
environment and to serve the `mounted filesystem table'.
