thousands of warnings from UPP code from gfortran

[edwardhartnett]

When I run UPP through gfortran I get thousands of warnings.

I presented these results in a slideshow to the UPP team some time ago, and there was not much interest. But I am opening an issue to record this.

Build with gfortran -Wall and you will find many defects in UPP code that should be cleaned up. I suggest you clear all warnings and then set up the CI system to prevent careless programmers from introducing more.

Here's the slide about warnings in your code from a presentation about UFS code quality and issues. As the slide says, don't try and fix your warnings without unit testing first, or you will just break more stuff.

Thanks, Ed! Our software integration team is planning to write up a UPP unit testing plan this PI, and I think they will be in touch with you if they haven't been already. I suspect implementation will take quite a while, but it's at least on EPIC's radar. Thanks for creating the issue. :)

Glad to hear this code is getting some testing! Let me know if you need help.
