Comment (by kencu):

 So agreed that this port should not usually be deployed on macports with
 "-Werror" enabled (that is a dev thing).

 That said, this should not be happening, AFAIK:
 {{{
 extra options: '-march=armv8.2-a+dotprod -Werror'
 }}}

 all of these need to go:
 {{{
 error: implicit declaration of function ...
 }}}

 and then the big puzzle might be solved, if we get rid of this headache
 (by the above fixes?):
 {{{
 <stdin>:29:2: error: instruction requires: dotprod
 }}}

 then maybe {{{math.h}}} will preprocess right and this will disappear
 {{{error "Unsupported value of __FLT_EVAL_METHOD__."}}} as there seems to
 be absolutely no reason that {{{__FLT_EVAL_METHOD__}}} that is defined by
 the compiler (hopefully still is defined by the compiler, at least, as you
 showed above) to "0" will not properly be handled by the code you showed.

 What a mess.
