* Remove FUNCMATH from all void-returning functions, given GCC80 specifically complains about this case. * Extend the length of all extant buffers to the safety threshold recommended by the compiler. * Add void casts to WS_getaddrinfo's setting to prevent complaints about incompatible typecasts. * Extend the charsel, face, and superface buffer sizes and writes to include the null terminator. (I didn't really want to do this because it's not even particularily NEEDED, but there was literally zero way to get around the request that I could find with multiple online searches. I tried.)
