Comment (by michaelld):

 FYI if you want to "hack" math.h ... line 742 in the 12.2 beta currently
 reads:
 {{{
 #if defined __i386__ || defined __x86_64__
 }}}
 and IMHO should read:
 {{{
 #if defined __i386__ || defined __x86_64__ || defined __arm64__
 }}}
 to include support for ARM64 ... that is, unless Apple is explicitly
 dropping support for the legacy BSD API with the move to Apple Silicon ...
 hmmm ....
