Okay, I've added these definitions to GCC-XML.  It will be up to pyste 
to define them properly when invoking an older GCC-XML version that does 
not have this feature.

Below is a clip from the GCC-XML man page after these changes that 
describes the definitions provided beyond the simulated compiler. 
Please update gcc_xml.hpp to use these definitions to switch among GCC 
parser versions.

Thanks,

The following extra C preprocessor definitions are provided:

   -D__GCCXML__=MMmmpp
     MM, mm, and pp are the major, minor, and patch versions of GCC-XML.
     This preprocessor symbol identifies GCC-XML to the source code as it
     is preprocessed.  It can be used to enable GCC-XML-specific
     information.

   -D__GCCXML_GNUC__=3
     Defined to internal GCC parser major version.

   -D__GCCXML_GNUC_MINOR__=3
     Defined to internal GCC parser minor version.

   -D__GCCXML_GNUC_PATCHLEVEL__=2
     Defined to internal GCC parser patchlevel.
