The sources are freely available to everybody (in v2/djlsr201.zip), so 
you don't need to be a wizard to hunt such bugs down.

However, in this case, I think there's nothing to fix, since `system'
doesn't allocate any DOS memory.  And on MSDOS I have never seen any such
problems, although I have run Make on large distributions where it calls
`system' much more than 50 times.  It might be something specific to the
Windows 95 DPMI host (it is known to leak selectors, so might as well leak
DOS memory).
