Unfortunately GCC doesn't have any pragmas for turning warnings or
errors on and off like that, they're controlled by the command-line
only, and they affects the whole translation unit. (There is a project
underway to provide more fine-grained control but that doesn't help
now.)

Neither is there a macro that tells you when -pedantic has been
requested. And even in the latest development compiler's C++0x mode
this is still an error.

Tough call - if you want the library to be usable with -pedantic
(which is a reasonable feature for people to request) then you'll have
to forego the trailing comma :-(

This layout
enum { foo
     , bar
     , baz
     };
helps prevent the same copy'n'paste errors, but isn't to everyone's
taste (although it does work in other lists, not just enum
declarations, which is why some people use it.)
