c23 compilation failures

Description
-----------

Fedora is moving to gcc 15 in rawhide, which has -std=c23 by default. Gambas3 does not compile with this revision of the C standard because it uses functions without arguments defined.

gbx_event.c: In function ‘EVENT_check_post’:
gbx_event.c:247:26: error: too many arguments to function ‘save.func’; expected 0, have 1
  247 |                         (*save.func)(save.param);
      |                         ~^~~~~~~~~~~ ~~~~~~~~~~
In file included from gbx_event.c:32:
gbx_event.h:41:12: note: declared here
   41 |     void (*func)();
      |            ^~~~
gbx_event.c:249:26: error: too many arguments to function ‘save.func’; expected 0, have 2
  249 |                         (*save.func)(save.param, save.param2);
      |                         ~^~~~~~~~~~~ ~~~~~~~~~~
gbx_event.h:41:12: note: declared here
   41 |     void (*func)();
      |            ^~~~

Easy enough to work around, it compiles fine with -std=c17 in CFLAGS, but probably something you'll want to fix.


System information
------------------

Fedora x86_64, though, that probably doesn't matter here.
