It all depends on the functionality needed in mmap().  Full functionality 
needs some DPMI 1.0 call support.  I have made portions of mmap() available 
under DJGPP in the past under CWSDPMI (for protecting/unmapping/demand 
mapping pages).  But most applications can be coded around needing mmap() if 
it just to pull the contents of a file into memory.

modify_ldt() should be able to be implemented using DPMI calls (or coded to 
use the DJGPP equivalents instead)
