Browse Source 
* add forgotten template argument to make_format_args which made some uses of FMT_COMPILE not work anymore after 54daa0864a, add more elaborate test cases to compile-test as regression tests

* fix old-style cast which gcc on travis thankfully doesn't accept anymore

* hopefully last forgotten (void*)
