Have you tried D language? The D language author is the same author of Zortech C++, the first native C++ compiler for 16/32 bit MS-DOS. Perhaps if you have any problems in compilation, he probably can help.
So what you are saying is that some oldish version of DLANG compiler can actually run on MSDOS as it does have Zortech C++ compiler from 1993 as backend?
This is still "cheating" - but VERY promising! Thank you sir.
Any chance for link to actual MSDOS compiler in such old version?
