make's output when attempting to build libheif

When building libheif on 14.1-STABLE I get the following error:

/usr/include/c++/v1/csetjmp:40:6: error: "If libc++ starts defining <setjmp.h>,
the __has_include check should move to libc++'s <setjmp.h>"
   40 | #    error "If libc++ starts defining <setjmp.h>, the __has_include
check should move to libc++'s <setjmp.h>"
      |      ^

I've included the output of make > make.out 2>&1 as an attachment.

Because this behavior first surfaced immediately after I upgraded my system
from 13.3-STABLE to 14.1-STABLE it is possible (probable?) that this is a
problem I introduced.

The workaround to get past this and create a usable build is to add #if
0/#endif around the #error in /usr/include/c++/v1/csetjmp which feels very
dirty and wrong.

$ uname -a
FreeBSD tms.home.galassi.us 14.1-STABLE FreeBSD 14.1-STABLE
stable/14-n267830-339b47f01985 GENERIC amd64

This behavior is currently observed with /usr/ports at commit
3b0403f7946050b0b582f905c6b2d0e3dc929cf1

make config enables only the default options (all except for RAV1E)
