libzzip @0.13.72: error: incompatible pointer to integer conversion

[rrobtoo (Robert K.)]

Dear DevTeam,
The port upgrade outdated fails with the following error, but manual compilation of the newest version of libzzip 0.13.74 works just fine.

Please find below the error log:

Yup, this (treating the int-conversion warning as an error) is new in Xcode 15.3.
