I have both

It all works OK.

I found I needed to copy the HDF .dll files into the same directory as the
.exe file, otherwise dynamic loading
had problems. The main thing you need to be careful about in makefiles is
that windows compilers & linkers
need file paths in windows form (e.g. "C:\mydir\prog.c" rather than
"/c/mydir/proc.c").  You can use the cygwin
utility "windows_path" to automate this name conversion.
