#### clang 3.4 ####
$ clang -target i686-w64-mingw32 -nostdinc \

-isystem /opt/other/mingw/i686-w64-mingw32/include \
test.c
works.
#### clang - trunk / 3.5 ####

----
It would be great if clang could accept such header files with a warning
instead of an hard error, as this renders the MinGW target quite unusable
with certain header files included.
