The original homeworld tools were MS-environment based command line utilities.
My thought is to wait and see what HW-SDL has done since it went off the air, and then start doing direct translations of still-needed tools using...
g c c / + + 4.0.1
Hmmm... it FINALLY worked. The new security module for phpBB apparently throws a fit if you mention the Gnu C Compiler by its commonly used initials.
Which is rather inconvenient for a forum devoted to coding, dontchathink?
I know the 4.0 version of g-c-c hasn't endeared itself with its stricter adherence to standards and cutting of some popular legacy code support, but it seems that using that standard for the needed tools will insure a long life for the new codebase, and, of course, the most easily ported code.
