MinGW compatibility about screenfetch-c

[woodruffw]

Thanks for bringing this to my attention! It's interesting that screenfetch-c builds at all with MinGW - I would have guessed that at least some of the external functions I used via cygwin would be undefined.

Unfortunately, I no longer develop actively on Windows, so I'm not sure if this is something that I will ever personally work on. screenfetch-c is mostly in maintenance mode - I haven't added any significant features to it in the last year or two.

That being said, I'm more than happy to review and merge any commits you have towards this goal. I'm not sure what conhost uses for console colors (I thought it used ANSI codes like the ones screenfetch-c emits), but that should be a pretty quick fix. Similarly, the simplest way to circumvent the missing unix/POSIX functions is probably to create a new src/plat/mingw subdirectory and corresponding make target.

Closing this issue.

I may open a pull request later to add information to the README on how to use a MinGW build with Batch and PowerShell scripts.
