Move inclusion of system headers in misc.c to top, which fixes building on

recent Cygwin (including windows.h after the macros defined in modval.h
causes the build to fail due to our 'load' macro).  Reported by VICODAN.

Also define WIN32_LEAN_AND_MEAN in misc.c, which should speed up Cygwin
build times a little.
