@subsection Native Windows compilation using MSYS2
The MSYS2 MinGW-w64 environment provides ready to use toolchains and dependencies
through @command{pacman}.
Make sure to use @file{mingw64_shell.bat} or @file{mingw32_shell.bat} to have
the correct MinGW-w64 environment.
@example
# normal msys2 packages
pacman -S make pkgconf diffutils
# mingw-w64 packages and toolchains
pacman -S mingw-w64-x86_64-yasm mingw-w64-x86_64-gcc mingw-w64-x86_64-SDL
@end example
To target 32bit replace the @code{x86_64} with @code{i686} in the command above.
