GCC 15 and sendmail and milter?

[AMM]

Hello

Happy to see new release 8.18.2 coming after more than a year!

Also GCC 15 is coming too.

Just wanted to point out that as per bug link below, currently sendmail
milter related packages do not compile with GCC 15.

https://bugzilla.redhat.com/show_bug.cgi?id=2336394

I would request if this bug can be fixed in 8.18.2.(-std=gnu17 is a
workaround to force GCC 14 behaviour)

Also as per bug report - it is not clear if API/ABI will have any
issues. i.e. if may affect all milter packages?

Clarification regarding this would be appreciated.

Thank you,

AMM

Is SM_CONF_STDBOOL_H defined for the platform?

From .spec or redhat.config.m4 file, I dont think so.
https://src.fedoraproject.org/rpms/sendmail/blob/rawhide/f/sendmail.spec

But defining SM_CONF_STDBOOL_H will break backward compatibility with
GCC 14. As it does not have stdbool.h

I am not an expert but may be something like this may work inside mfapi.h?

#ifdef __GNUC__
# include <features.h>
# if __GNUC_PREREQ(15,0)
# define SM_CONF_STDBOOL_H 1
# endif
#endif

// line 92 of mfapi.h
#if SM_CONF_STDBOOL_H
...

See include/sm/config.h, that's where SM_CONF_STDBOOL_H is handled.
Maybe you can write and test a patch (with GCC 15 and older versions)?
