more warnings

[Indy Sams]

Hello Dennis,

I've seen this warning before in other projects "dereferencing
type-punned pointer will break strict-aliasing rules" (wxWidgets
specifically), but anything I've built seemed to work fine so I
wouldn't worry about it.

I haven't seen the other 2 warnings, "pointer targets in passing
argument 3 of ‘...’ differ in signedness", so I don't know about
those.

On Windows, I usually compile it in MSVC but I don't use CMake @ all
I just created a project in MSVC directly.
