ack/plat/pc86/emu/x86emu/x86emu/debug.h
George Koehler 5404dace3a Stop using <X11/Xfuncproto.h> from x86emu. 
The code included <X11/Xfuncproto.h> only for _X_ATTRIBUTE_PRINTF,
which tells some compilers to check the printf format string.  Remove
so ACK doesn't need any X11 headers.

Some machines don't have the X11 headers, or they need a flag like
-I/usr/X11R[67]/include to find them.
