LC was available for a wide variety of platforms. We ran Lattice on a non-PC compatible (80186 with no memory-mapped display) To quote the page I pointed to:
"Lattice C was ported to MVS, VMS, Unix, OS/2, Amiga, Atari ST, and Sinclair." My point being that the file I/O of the system hosting the compiler would be used. If you're running it on an x86-based MSDOS OS, you'll use MSDOS I/O. That does not imply a PC, only an x86 machine that can host MSDOS. If you want vintage, I think that there's a K&R C source on github: https://github.com/AoiMoe/knrcc Some time ago, I revisited some code I wrote in the late 1970s-early 1980s and found that gcc didn't like it at all. As mentioned, there are a host of C cross-compilers. --Chuck
