BDS C is irretrievably broken, with all sorts of things missing. I used to use Hi-Tech C for CP/M, but I don't know whether they're still in business. It was a full ANSI C compiler, with function prototypes, initialisation assignments, static variables, etc. As Henry Spencer once said, to be called a C compiler it ought to at least be able to compile C... (And as I've said on many occasions, the true test of a compiler is whether it can compile itself.) -- Dave Horsfall DTM (VK2KFU) "Those who don't understand security will suffer."
