/* Operating system specific defines to be used when targeting GCC for
   hosting on Windows NT 3.x, using the Cygnus API 

   This is different to the winnt.h file, since that is used
   to build GCC for use with a windows style library and tool
   set, winnt.h uses the Microsoft tools to do that.
