Comment (by thorbenj-macports@…):

 Adding "-Wunused-command-line-argument-hard-error-in-future" doesn't work:

 {{{
 :info:build clang: error: unknown argument: '-module' [-Wunused-command-
 line-argument-hard-error-in-future]
 :info:build clang: note: this will be a hard error (cannot be downgraded
 to a warning) in the future
 }}}

 OR, maybe port invocation is to blame:

 {{{
 # port install llvm-gcc42 configure.cflags-append "-Wno-unused-command-
 line-argument-hard-error-in-future"
 }}}

 Which is what I understood from:
 https://guide.macports.org/chunked/reference.phases.html#reference.phases.installation
