Syntax error while installing with bundled fltkhs

[chenyulue]

I got the following error:

fltkhs > make[1]: Leaving directory '/c/Users/chenyulue/AppData/Local/Temp/stack-bcc533c003cb80ea/fltkhs-0.8.0.3/.stack-work/dist/29cc6475/build/c-src'

-- While building package fltkhs-0.8.0.3 (scroll up to its section to see the error) using:
C:\Users\chenyulue\AppData\Local\Temp\stack-bcc533c003cb80ea\fltkhs-0.8.0.3.stack-work\dist\29cc6475\setup\setup > > --builddir=.stack-work\dist\29cc6475 build --ghc-options " -fdiagnostics-color=always"
Process exited with code: ExitFailure 1

What's wrong with it? The command to build it is stack install --flag fltkhs:bundled --flag fltkhs:opengl in the fltkhs-hello-world directory on windows os.

However, if I run the command stack install --flag fltkhs:bundled, the package is installed successfully. So what's wrong with opengl? What else should I do if I want to build it with the flag fltkhs:opengl?

This is a fix that needs to be made in language-c for c2hs, there's an odd construction in the MinGW header that only gets exposed if compiling with the OpenGL option.

You can add my patch for now with the following in stack.yaml:
