Notes and Limitations:

For certain F77 source files, when compiling with gcc/10+, it may be necessary to configure/compile with:

export FCFLAGS="-fallow-argument-mismatch"

export FFLAGS="-fallow-argument-mismatch"

This will turn mismatch errors between actual and dummy argument lists to warnings. See:
