commit 74eebed1d73023ebd7c2abc391492918272531f9
Author: Ian Lynagh <igloo at earth.li>

    Define _HOST_OS and _HOST_ARCH when calling hsc2hs
    
    In particular, old-time assumes that mingw32_HOST_OS is set when
    we are on Windows, and was going wrong on Win64 because it wasn't
    defined.
