Dear gnustep developers,
It is first time for me to submit something here.
msys2 is more convinient and updated than msys,
so I tried to build windows version of gnustep with it.
Some build tweaks are need to compile.
Though gnustep windows build seems to be rarely used,
it would be good that anyone having interest check my tweaks.
There may be some violation of patch submitting rule such as format or file which I have not noticed.
