// This stuff can go in some include file with other os-specific code.
// I removed the test for the compiler version, the availability  
macros predate any version of OS X that SL is going to run on.
// To use the XCODE_VERSION_ACTUAL the project will need to be  
modified to expose that constant as a macro.
#ifdef __APPLE_CC__
# include <AvailabilityMacros.h>
# ifdef MAC_OS_X_VERSION_10_5  /* Not defined for pre-leopard  
versions */
#  define YACC_GENERATES_HPP 1
# endif
# ifdef XCODE_VERSION_ACTUAL
#  if XCODE_VERSION_ACTUAL >= 0250 /* or 0300 */
#   define YACC_GENERATES_HPP 1
#  endif
# endif
#endif

// something similar for Windows can go here, if we want to revert  
the hack in the build tools

// then, replace the line including indra.y.h with this...
# ifdef YACC_GENERATES_HPP
#  include "indra.y.hpp"
# else
#  include "indra.y.h"
# endif

Incidentally, I think there's a bug in Apple's docs. 0250 is 168  
decimal. If Apple's actually using that manifest constant in their  
include files they're going to be very unhappy when they get an xcode  
version with a minor version greater than 7. :)
