FYI...the variadic macro __VA_ARGS__ did solve the braced items problem on
array initialization in nested macros.  Just have to move the argument to the
end of the macro...

Thanks

Mike

You can use a variadic macro that allows multiple preprocessor tokens separated
by commas.

There's no GCC bug here.

So how does one get this to compile then..Can't seem to find any combination of
parentheses that works.  I'm converting an entry in the hamlib project to an
array and that's what is causing this problem with static initialization of the
array.

In the C preprocessor without a '(' everything after the ',' is the next
argument.
