* Fixed -Wunused-local-typedef warning * Fixed -Wformat warnings In one case also removed a `z` character. There was a `z%d` that I think was supposed to be `%zd` * Fixed -Wshorten-64-to-32 warnings * Fixed -Wself-assign warnings * Fixed -Wreserved-id-macro warnings * Commit format changes from clang-format, clang version 10.0.1. * Fixed -Wself-assign warnings * Fixed -Wunused-local-typedef warning * Fixed -Wformat warnings In two cases also removed a `z` character. There was a `z%d` that was supposed to be `%zd`. * Fixed -Wshorten-64-to-32 warnings * Fixed -Wreserved-id-macro warnings * Fixed -Wself-assign warnings * Format source. * Remove blank lines to pass format check.
