I was attempting to build the new ocl (1.2.2) release under macOS 13.6.1
(arm64) against my MacPorts octave 8.4.0 installation. I get the following
build error:

-I/opt/local/include/octave-8.4.0/octave -I/opt/local/include  -pthread -pipe
-Os -std=c++11 -stdlib=libc++
-isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX13.sdk -arch arm64
