Ok I would still argue against registering evrything at once just for reasons of
tidiness. OK I appreciate that its much more work though, so my 2nd choice would
be to go for the 2nd approach where a common named file is included  to register
all the types for a library:

1 personal 'thing'  for minimising macros
2 its easier to catch errors in a file name than #ifdef X
3 Its slightly more work figuring out the correct macro name than one common
file name
4 Single file approach  easier to manage as all registrations are in one place.

Has the third approach using a macro got any advantages over file inclusion
(2nd) approach?
