### Description

Trying to install php 8.3 on older macOS with the default system compiler fails:

It does build fine with gcc 13.2.0, however. (So no issue with older macOS as such.)

Can this be fixed for gcc 4.2 or should we just switch to using a newer compiler for
those systems in Macports?

### PHP Version
