Hi Martin,

2 ways to achieve this:

(i)  either the implementation module could
  #include <header.h>

CONST
   m2_major = CPP_VERSION_MAJOR ;
   m2_minor = CPP_VERSION_MINOR ;   (* etc *)

and set some record constructor which is initialised to these
values.  You need to compile the implementation module using -fcpp.

(ii)  or possibly write a C wrapper implementation module, write a
      M2 definition module for C and export the function which returns
      a C constructor.

there are probably other ways but these are the two I would consider first,

regards,
Gaius
