Comment (by JDLH):

 This bug is blocking me from recompiling `cairo
 @1.16.0_1+quartz+universal+x11` at the moment.

 I use macOS 10.13.6 High Sierra, Xcode 10.1, and macports 2.6.4 (current).
 I currently have `cairo  @1.16.0_0+quartz+universal+x11` installed and
 active. It appears my last build of cairo was in December 2018.

 The revision @1.16.0_1 appears to be motivated by the crash in macOS 11.0
 Big Sur described in ticket #61586.

 My
 `/opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_graphics_cairo/cairo/main.log`
 has the same relevant error message as in the Ticket Description above:
 {{{

 multiple threads.  Define CAIRO_NO_MUTEX to 1 to acknowledge and accept
 this limitation and compile cairo without thread-safety support."cairo-
 base85-stream.c
 }}}

 My
 `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_graphics_cairo/cairo/work/cairo-1.16.0-i386/config.log`
 file contains numerous lines matching comment:3 above, of the form:
 {{{
 ld: warning: The i386 architecture is deprecated for macOS (remove from
 the Xcode build setting: ARCHS)
 }}}

 I will try the workaround from ticket:50800#comment:2, which appears to
 cause cairo's `configure` script to ignore all warning messages during
 configure. I worry that this might cause it to ignore valid warnings as
 well.

 ticket:50800#comment:4 cites some upstream bug reports. I haven't looked
 up those yet, to see if upstream has a better fix.

 (Um, if Xcode doesn't support i386, why are we compiling for that
 architecture?  How will the tool even let us?  Can we just stop trying to
 compile Cairo for i386? I am really in the dark about how architectures
 are handled in MacPorts. I'm not griping, just wondering.)
