Fair comment, I guess that there will not be many other apps that know the 
C define but not the Perl/Gtk string.

Yes, I was thinking of doing the $Gnome::Stock{'GNOME_STOCK_BUTTON_OK'} 
just once when I build the source code and thereafter using the looked up
string when the source was run, but I can see your point, it would be very
inefficient in any case but mine.

You are right, I guess that it would be better to search the header files
for each C define rather than generating a giant hash for every run. I will
have to see whether there would be savings if I generated a lookup module
in my Makefile.PL.

Thanks for your time, I will stop going on about this now :-)
