    Since I don't believe that xconfig will currently configure this information,
you would have to

           i) extend xconfig (some tcl/tk programming) to write a version_config
file
         ii) replace the version info in the top level makefile with an include
statement of this new file.

 you could also write perl or  awk program to modify the makefile when you get a
new distribution. It could
remove the versioning macros and replace it with an include statement of the file
you write out during the
x-configuration process.
