I have different mingw compile on Debian stable and unstable. This
makes the check run on both my systems.
Note however, that with i686-w64-mingw32, compilation currently fails.
check-windows:
mkdir -p _check-win
- cd _check-win && ../configure --host=i586-mingw32msvc CC=i586-mingw32msvc-gcc
+ cd _check-win && ../configure --host=i586-mingw32msvc CC=i586-mingw32msvc-gcc || \
+ ../configure --host=i686-w64-mingw32 CC=i686-w64-mingw32-gcc
cd _check-win && $(MAKE)
check-autotools:
