mingw-runtime-1.1.tar.gz has to be extracted under the ./mingw32 folder.
Files come with /include/ or /lib/ paths attached.
However six files within the downloaded archive have already a
./mingw32/... path attached (gcrt1.o, gcrt2.o, gmon.h, libgmon.a,
I guess these should not create an extra branch ./mingw32/mingw32...
with /include and /lib subfolder ?
Should I put them into the same folders ./mingw32/include or
.mingw32/lib as their predecessors ?
