from a brief experiment, the /GX switch seems to be OK with C sources too (probably no effect?). For prudence, however, my approach had been to add it only when compiling C++ sources -- that's easy too given the way the loop is set up now (there's already an if/else to set the /Tp or /TP switch for the sourcecode; I just added another variable, to be concatenated at the end, set to either  or ['/GX']). That's probably more prudence than actually needed here, I guess.
I'm checking in the easy-cheezy approach: use /GX when compiling anything. If it doesn't work for C code, we'll find out soon enough.
