Anyone out there with experience in porting UNIX/X11 applications to
MSDOS?

We are investigating the possibility of porting a rather big UNIX/X11
application (about 25 Mb source) written in FORTRAN and C to MSDOS.
The reason we want to port to MSDOS is that a lot of people have a PC
that is adequate for our application, but the do not want to leave
MSDOS becouse of existing applications, or they do not want to learn
a new OS like for example UNIX.

What dit you do about the following problems:
- Limited file name lengths
  The development will continue on UNIX, so for sources i would not mind
  to convert file names automatically.
- Memory - UNIX has an "unlimited" virtual memory space for every proces
  Are there compilers or other methods to have an "unlimited" address
  space under MSDOS (or maybe Windows NT) ?
- Can linkers under MSDOS handle long routine names
  Our routines are unique within 9 characters.
- Can you combine C and FORTRAN code the same way you do under UNIX
  i.e. trailing underscore and extra parameters for stringlenths for
  FORTRAN routines
  Note: we could prevent the problem of combinig C and FORTRAN by converting
  our FORTRAN code to C using F2C.
- What dit you do about graphics, we currently use X11

Other things I would like to know are:
- What compilers and utilities dit you use
- Where can they be obtained (reps in The Netherlands or elsewhere in Europe)
_ What was the approximate cost

Are there any problems i dit not mention that i should think of?
