GCC-15/C23 issue.

The bool part is easy, but then we have another instance where () was used to typedef a function type that takes any number of (i.e. an unspecified number of) arguments. In C23, there doesn't seem to be an easy alternative except to add casts everywhere and nobody wants to do that.
