Indeed, the msdos target exists, but it's not in the distribution on the FreeDOS host.
I've changed to using the TP compatibility mode, and that has resolved most of the problems. Now, my biggest problem is getting far pointers to work, since they're only enabled for msdos. I'm attempting to compile the msdos compiler, but fpcmake is failing due to a missing Makefile.fpc in the utils directory in the source tree. Happy Hacking, David E.
