That would make this commit simpler.

There could be a bigger problem though -- in theory the debug(),
error() etc macros should only be used from library code.  Your new
osinfo code is now being used as common code.  Now there are a few
ways to resolve this:

(1) Move debug(), error() etc to common/utils.  I'm not sure this will
actually work since they depend on g->verbose which is a private field
in the handle.

(2) Remove use of debug(), error() etc from the new mini-library.
Problem goes away completely if you can do this.

(3) Move the mini-library under common/osinfo (cf. common/visit for a
similar example).  Dependencies may make this difficult, but may also
point to problems.

Possibly (2) & (3) ...

Rich.
