My feeling is that Linus' reaction was more about that this
work-around is even necessary (and MinGW is buggy) rather than
applying it to git-compat-util.h and not elsewhere.

I just don't like that the ugliness is spreading out and requires a
change to config.mak.uname now, too. Also, I regard the change to
config.mak.uname by itself as ugly, mainly because you would have to
set SYSTEM_STRING_H_HEADER to some path, but that path might differ
from system to system, depending on where MinGW is installed on

I tried to put the __NO_INLINE__ stuff in compat/mingw.h but failed,
it involved the need to shuffle includes in git-compat-util.h around
because winsock2.h already seems to include string.h, and I did not
find a working include order. So I came up with the following, do you
like that better?
