I did the port of v1.29 to S/2 using the Borland C (for
The .zip file includes an 00readme.os2 file which gives
changes I made.  In a nutshell:

-   the optimised "direct video" screen module (screen.c
    OS/2 VIO services are used instead (via text window

-   the modified DOS system() call that uses clever tric
    the current program before executing a child program
    under OS/2;

-   fixed a handful of bugs that caused access violation
    NULL pointers);

-   a new module "os2fixes" that provides some services
    not directly available under OS/2;

-   version now reports "SNEWS for OS/2";

-   support for the "maildelivery" option in SNEWS.RC.

-   there are no longer any RAM problems

If the NULL pointer bugs have been fixed, "maildelivery" isn't needed and
you now have DPMI support, the DOS version ought to be perfectly
adequate for the task.

I'm afraid I haven't used OS/2 for a long time so I can't offer to help.
