+I took a look at compiling gridengine with mingw.  Current stumbling block is
+that mingw32-w32api does not have pdh.h/libpdh.a (pdh.dll) from the Windows SDK.
+
+The patch gridengine-mingw.patch adds a -mingw32 flag for aimk to use for the
+compile step after dependencies have been generated.  (Strange, but you need
+native tools to generate the deps)
