Since the toolchain is GCC, on top of Cygwin, I'm pretty certain that your# include path of "c:\Temp\new\alt_up_audio.h" will not work.

Also, it's better practice to limit this to something like

# include "alt_up_audio.h"

...and then to add include paths to your project under the "C/C++ Build" options, if using the IDE.

If you're using your own custom build environment, then you'd need to (at a minimum) include a -I gcc command line switch.
