This only makes the problem much worse. (Note that I literally reference MSys and Cygwin in my original reply. However, these options are neither ideal for making good Windows binaries nor are they great facsimiles for UNIX. Almost any Makefile needs to be carefully constructed so that MinGW works, especially if you want to support more than just very specific MinGW setups. And there's other downsides I didn't get into, such as licensing problems with winpthreads, and silent dubious behavior like pseudo relocs. I don't recommend using MinGW.)
