   You want something like this in gnulib?

   #define ARGP_PROGRAM_DATA (command, authors) \
   void argp_program_version (FILE *stream, struct argp_state *state) \
   { \
     version_etc (stream, command, PACKAGE_NAME, PACKAGE_VERSION, authors, \
                       (char *) NULL); \
   } \
   void (*argp_program_version_hook) (FILE *stream, struct argp_state *state) = 
\
          argp_program_version; \
   const char *argp_program_bug_address = "<" PACKAGE_BUGREPORT ">"; \

   So the user program does:
   #define AUTHORS "Foo", "Bar"
   ARGP_PROGRAM_DATA ("myprogram", AUTHORS)

If that works, it might be a good idea.  But it should be thought
about carefully before adding it to gnulib, would suck to change it
alot later on.  One could use global variables instead of macros as
well.
