minilua | Single-file port of Lua, a powerful scripting language | Game Engine library

I took a quick look:

The warning about conversion from 'int' to 'HANDLE' of greater size are probably due to a missing #include , which leads to the compiler assuming that _get_osfhandle() returns int instead of intptr_t. This is potentially a bug (though it might not manifest in practice depending on the range of values windows actually returns from that function).

The warnings about 'FARPROC' differs in parameter lists are due to missing casts from the generic pointer returned by GetProcAddress() to the specific type. However, because all pointer types have compatible representation, nothing bad can happen if ignored.

The warnings about the pragmas can be ignored as well, and could be suppressed with a judicious use of #ifdef __GNUC__.

The warnings about unrecognized character escape sequence are due to not properly escaping backslashes in paths in generated code. Should be fixed, but can be ignored as well.

Regarding zstd, the configuration script uses pkg-config to find the library, so no windows support. Someone should fix that. However, I believe this will only affect the profiler, not regular operation of MoarVM.

I did not investigate the Command line warning stuff, though it looks like something thinks it's compiling on a *nix system and hence passes incorrect flags. Should be fixed, but might not break the build.
