Comment:

 We saw the same error on systems as new as macOS 10.15:

 https://build.macports.org/builders/ports-10.15_x86_64-builder/builds/98836/steps
 /install-port/logs/stdio

 but then Marius conmitted [874b9b8ca44c29b72455d722a5dd54e312c0e820
 /macports-ports] which fixed the build on all buildbot systems (10.6 and
 up). Does that help your systems? If not maybe a different `-std` needs to
 be specified. I see that Marius's fix included removing `-std=c99` and
 telling MacPorts to pick a C11 compiler, but there is no corresponding
 `-std=c11` flag in your log.
