Standalone Program for Testing fargparse

The error logging may eventually evolve into a module based on the ESMF logger. For now these macros provide simple traceback capability. new Old New Assumes status is passed back in dummy called “rc” Assumes “/home/runner/work/MAPL/MAPL/include/MAPL_ErrLog.h” and 125 are appropriate The following macro causes a variable to appear to be “used” according to the compiler. This is a kludge to avoid excessive warnings. In most cases, a better fix would be to modify the the procedure interface, but it is impractical in the short term.

Note that the conditional is never satisfied and a reasonable compiler will optimize the line away. (Hopefully without reintroducing the warning!)
