[McIDAS #TTX-917770]: McIDAS 2006 nav_init issue

Hi Joseph,

> We are in the process of upgrading from McIDAS 2003 to McIDAS 2006 and ran
> into a problem compiling mci_nvpp. The compiler complained about several
> undefined symbols, and examining the makelog showed that nav_init was
> generating unusual nav types from the navigation modules: gpes, geps,

Interesting.  Can you tell us what operating system you are doing the build
on?  This will help to understand the problem more fully.

Yes.  I thought that the problem had been resolved outside of McIDAS.  Evidently
it has not.

> I thought I would let you know.

Thanks for reporting the problem.  I will fold the old fix back into the
Unidata distribution and make it available in the next addendum and full
