I was wondering if we should handle operator precedence correctly, like in `1 + 2 * 3`. With this PR, we currently evaluate addition first, resulting in 9. GNU windres seems to handle precedence properly and gives 7. MSVC rc.exe is odd, it appears to ignore multiplication and division entirely, just outputting 3.

I'm not sure what the best approach is here, what do you think?
