I initially had config.h included into std.h, but then decided to take it
out to clean up the object space of all objects.  So long as I remember to
include config.h along with the other kernel header files that I need for a
given operation, I'll be good to go.

I merely noted that the macro issue produced a less informative error if in
a funcspec in case you wished to expand on it in the source, if feasible.
;)  Also as a warning to any other DGD newbies reading.

Aha, that'll do the trick.  Thanks. ;)   I probably read that a million
times in the archives and documentation, too.  I'm having a lot of fun with
this driver.  I get confused a lot, but that's normal for me.  The
information I need is scattered all over the place and I often can't
remember what I'd read from the archives or documentation when I'm
elbow-deep in coding something.  Back to the grindstone!

Thanks, again!
