`.pc` file doesn't work on MinGW

[jasagredo]

The Cflags of this package include a -I/mingw64/include which is not translated by pkgconf to a Windows path leading to further errors later on (in this case in ghc-pkg).

See haskell/cabal#9479 (comment)

@jasagredo I don’t see hardcoded references to /mingw64 on this repo. Maybe you are refering to the generated .pc file?

Even so, I can use it just fine on Windows environments with pkgconf and vcpkg, and also on MSYS2.

Is this still reproducible?

It has been more than a year and a half since I reported the issue. I am not currently using Windows on a daily basis, so I cannot tell whether or not this is reproducible still
