Again unable to build on macOS (M1, Ventura 13.4)

[Yserra]

Hi David,

All previous source code compiled without issue.
I just tried to "gmake" the latest source code (on June 11th, 2023) on my Mac M1/macOS Ventura 13.4 (my Homebrew tools/libraries were updated just before building). Here are the errors I get:
