What you (and everyone else) ought to do is write your program in a
modular fashion, and isolate all the platform dependencies so they can
be easily replaced.

If your program is a game or similar interactive graphical program, you
will probably have..

- User Input
- Timer
- Graphics
- Sound

..as the dependent sections.

I render all my graphics onto a framebuffer using my own routines, and then
I can blast the framebuffer to the display using specific routines for DOS
'95 linux or whatever.

For sound I am using a version of mikmod which is driver-based and can compile
for output in most OSes.

The timer is DOS-specific, but essentially anything which can call my function
n times per second will do perfectly.

I think that this is the sort of thing you should aim at, since you will then
be able to make versions for many platforms with little effort, and thus
please several groups of users instead of just one.
