Make fails on windows 10

[yusijs]

So I've tried with both nmake from vs studio express 2015 and WinGNU make, and neither works. Any pointers on how to build this project?

WinGNU make

make

It builds with MinGW, please see build steps in appveyor.yml file.

Fab, thanks, I'll give it a whirl!

If anyone else happens across this:
MinGW can compile this fine, but add CC=gcc after make all. Otherwise it'll fail with "cc: unknown command"
