drop `-Wpedantic`: it doesn't serve any practical purposes. instead, identify a set of warnings that you care about, and use them. in this particular case, we're talking about undefined behaviour that every compiler that is not a university student project, or an arcane compiler for a niche architecture, supports anyway. in practice, everything that GLib supports, will also support this construct. ciao, Emmanuele. > 2014-08-22 18:29 GMT+02:00 Emmanuele Bassi <eba...@gmail.com>: >> hi; >> >> On 22 August 2014 17:10, Iñigo Martínez <inigomarti...@gmail.com> wrote: >> >>> I am trying to figure out the best way to use function pointers as >>> values in a GHashTable.
