Failing to cross compile for windows 32 bit: error: conflicting types for ‘ssize_t’

[zsoerenm]

I failed to cross compile the windows 32 bit binaries using i686-w64-mingw32.

mkdir host/build
cd host/build
cmake -DCMAKE_INSTALL_PREFIX=$prefix\
  -DCMAKE_TOOLCHAIN_FILE=${CMAKE_TARGET_TOOLCHAIN}\
  -DCMAKE_BUILD_TYPE=Release\
  -DENABLE_BACKEND_LIBUSB=TRUE ..
make

It fails with:
