little warnings when building celestial_navigation_pi

[filochard]

Hi Rick and Dave

I get some warnings when building this plugin, they are harmless and don't prevent to build,
but maybe some little corrections are needed to some parts of the source

celestial-navigation-warning.txt

hoping this will help
Best Regards

Hi Rick
I'm not skilled enough to correct the source
Those "warnings" don't prevent to build : they are not "errors"
This not an emergency !
They are here to inform developers using and knowing C and C++ that something should be corrected in the .cpp files or .h files

I think that Alec or Dave or others developers have this skill

PS

It may be useful to add that I use gcc 12.3.0 and gcc-c++ 12.3.0 to compile
