I thought he was running DJGPP under DOSBox and not directly under
Windows 7.  DOSBox is designed to be able to run old games, so not
even long filenames are implemented.  How about trying some other kind
of virtual machine, eg. QEMU or VMWare?

I've said it before, but NT series Windows support for DOS programs is
pathetic (and on 64-bit versions it is nonexistent).  Then again,
Linux never directly supported DOS programs at all.  In both cases,
virtual machines are the solution.

Cheers,
Albert.
