Some of the code, especially the dshow and windows codec loader parts, are extremely hacky and likely full of bugs. The goal is merely getting rid of warnings that could obscure more important warnings and actual bugs, instead of fixing actual problems. This reduces the number of warnings from over 500 to almost the same as when compiling on Linux. Note that many problems stem from using the ancient wine-derived windows headers. There are some differences to the "proper" windows header. Changing the code to compile with the proper headers would be too much trouble, and it still has to work on Unix. Some of the changes might actually break compilation on legacy MinGW, but we don't support that anymore. Always use MinGW-w64, even when compiling to 32 bit. Fixes some warnings in the win32 loader code on Linux too.
