  Filename:	yaAGC.h
  Purpose:	Header file for common yaAGC-project functionality.
  Contact:	Ron Burkey <info@sandroid.org>
  Compiler:	GNU gcc
  Reference:	http://www.ibiblio.org/apollo/index.html
  Mods:		04/21/03 RSB.	Began.
  		08/20/03 RSB.	Added uBit to ParseIoPacket.
		10/20/03 RSB.	Defined MSG_NOSIGNAL for Win32.
		11/24/03 RSB.	Began trying to adjust for Mac OS X.
		07/12/04 RSB	Q is now 16 bits
		08/18/04 RSB	Added the __embedded__ type system.
		02/27/05 RSB	Added the license exception, as required by
				the GPL, for linking to Orbiter SDK libraries.
		05/29/05 RSB	Added AGS equivalents for a couple of 
				AGC packet functions.
		08/13/05 RSB	Added the extern "C" stuff.
		02/28/09 RSB	Added FORMAT_64U, FORMAT_64O for bypassing
				some compiler warnings on 64-bit machines.
