I'm not sure how to test it.

PDOS/386 supposedly doesn't work as host yet. HX hasn't been tested. Dunno if just using TinyC headers and libs would work (or OpenWatcom or MinGW or whatever).

If anyone finds out, please tell us.

(I have only lightly played with SubC and PicoC in DOS recently. Those are subsets, but I also have fuller C compilers like DJGPP and OpenWatcom and SmallerC that I sometimes use.)
