Comment (by ballapete):

 Actually `/opt/local/bin/gcc-apple-4.2` does not understand any of the
 `-Wno-<whatever>` options, `/opt/local/bin/gcc-apple-4.2 -v --help` shows:

 {{{
 -Wno-comma
 -Wno-date-time
 -Wno-deprecated-declarations
 -Wno-extra-semi-stmt
 -Wno-float-equal
 -Wno-format-nonliteral
 -Wno-implicit-fallthrough
 -Wno-missing-noreturn
 -Wno-newline-eof
 -Wno-nonportable-include-path
 -Wno-nonportable-system-include-path
 -Wno-pedantic
 -Wno-reserved-id-macro
 -Wno-reserved-identifier
 -Wno-shadow
 -Wno-sign-conversion
 -Wno-switch-enum
 -Wno-unknown-pragmas
 -Wno-unknown-warning-option
 -Wno-unused-macros
 -Wno-unused-result
 }}}

 Clearly they must be removed from `luametatex-2.10.08/CMakeLists.txt` – or
 `GCC7` used.
