Warnings as errors

[Y-Less]

Add something like -W to convert warnings to errors. A common flag in other languages.

This, I'd use this.

Because generally whenever I program and I get a warning, something in the code is wrong.

[Y-Less]

I've written a basic version (opted for -E instead of -W as it goes better with the existing -e). Testing now (if I can get a build working).

Does it mean that I'll get an error if a symbol hasn't been used yet?

[Zeex]

Yes, if you use the -E flag it will turn "unused symbol" warnings into errors (so the script won't compile).

Closing this because #202 has been merged.

[Y-Less]

You can still remove the symbol, mark it stock, use #prgama unused, or #pragma warning disable 203 and #pragma warning disable 204. There isn't much reason why you should be getting unused symbol warnings except during development.
