Hello. While building GMAT on Arch Linux with a recent f2c version (20200916-2) some typedefs in GMAT-R2020a/plugins/EstimationPlugin/src/base/measurement/Ionosphere/Ionosphere.hpp prevented building GMAT with a recent C compiler. It is my understanding, that in C you cannot test for existing typedefs and cannot have multiple with the same name even if the definition itself is the same.
Simply removing the following lines solved the issue and GMAT R2020a builds on a current Arch Linux.
