A very good question.

I use "info variables" to find definitions - and some information
about where they come from.  With all the declarations showing up I
can't figure out what file defined the variable, which I find
inconvenient.  Actually, I'd like it even better if I had the
memory location...

There's usually at least one definition, so the only thing the
declarations add is a list of files that (may or may not depending on
the whim of the compiler) have referenced the global variable.

Thoughts?  Anyone see a use for the declarations that I don't?
