They may not have heard about it, but they definitely know its properties. Lattice C is maiden name of Microsoft C and I doubt x86 developers who have never heard about Microsoft C exist.

P.S. Yes, Microsoft C 3.0 is independent rewrite but it had to be compatible with Microsoft C 1.x and 2.x and thus it had to be compatible with Lattice C, too.

I recall Microsoft C switched to signed characters in that rewrite, probably to be compatible with most Unix compilers. Xenix used Microsoft C as its system compiler, so compatibility helped porting. That is when I found out about the indeterminate behaviour of char in real life.
