SubC seems to be maintained again, but DOS support is broken. The latest DOS binaries date from 2014. It lacks some things (no strstr(), no sprintf(tmp,"%*.s",line), no goto, no parameterized macros) but otherwise compiles one very simple program of mine. It's very impressive, but SmallerC (BSD, 386+) is much more complete.
