@rem Because this is windows and *everything seems to hate Windows* we have to
@rem set all of these flags ourselves because Python won't help us (see the
@rem setup.py of the grpcio_tools project).

@rem Further confusing things, MSYS2's mingw64 tries to dynamically link
@rem libgcc, libstdc++, and winpthreads. We have to override this or our
@rem extensions end up linking to MSYS2 DLLs, which the normal Python on
@rem Windows user won't have... and ON TOP OF THIS, there's MinGW's GCC default
@rem behavior of linking msvcrt.dll as the C runtime library, which we need to
@rem override so that Python's distutils doesn't link us against multiple C
@rem runtimes.
