Changelog for libgsm-utils-1.0.pl19-7.178.fc40.x86_64.rpm :

* Thu Apr 29 2021 Dirk Müller - update to 1.0.19:
* Make it easier to include gsm.h from C++ by wrapping it with macros. Throw a #define _POSIX_C_SOURCE 200809L into toast.h to make it possible for Linux glibc to just work.
* Switch from compress/.Z to gzip/.gz
* Wed Aug 14 2019 Tomáš Chvátal - Small cleanups with spec-cleaner
