+/* 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.
