Comment (by kencu):

 Most likely this has been fixed upstream already to compile with the newer
 compilers. It's been a while since I went at the port... it's a bit job.

 FYI -- you can often find a simpler way to build things with older or
 other versions of compilers by using the MacPorts-supplied line of
 llvm/clang compilers.

 For this port, either clang-9.0 or clang-10 probably would have worked.
 Many people already have llvm-9.0 installed for one reason or another
 anyway, so you can do this if you like, instead of changing your Xcode
 around:

 {{{
 sudo port install clang-9.0
 sudo port -v install webkit2-gtk configure.compiler=macports-clang-9.0
 }}}

 Now perhaps you don't mind moving your Xcode's around -- I find it very
 hard to keep track of what I left where, and mismatched Xcodes and CLTs is
 a terrible mess. So this is a (probably easier) alternative.

 For really old and unmaintained ports, sometimes going back to clang-5.0
 is effective; I forget just now how far back clangs can go on Catalina.
