--- Comment #2 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
It sounds like what you want is an "IDE mode" for output, which could be
basically the same as LANG=C, but as a command-line flag.

Am I right in thinking that you want to be able to suppress just the
translation of "error" and "warning" etc, so that instead of output of the
form:

[with LANG=ja_JP.utf-8]

/tmp/test.cc: 関数 ‘int x2()’ 内:
/tmp/test.cc:3:4: エラー: some translated message here
 x0 x3 = x3.
    ^~
/tmp/test.cc:1:7: 備考: some other translated message here
 class x0;
       ^~

you get:

/tmp/test.cc: In function ‘int x2()’:
/tmp/test.cc:3:4: error: the same *translated* message here
 x0 x3 = x3.
    ^~
/tmp/test.cc:1:7: note: again, the message is still translated here
 class x0;
       ^~

i.e. that the content of the messages themselves should still be translated,
even when in some kind of IDE mode; it's just the "error"/"warning" etc
boilerplate that shouldn't be?

As of gcc 7 we already have -fdiagnostics-parseable-fixits; presumably you'd
want some kind of -fdiagnostics-output-format=VALUE or somesuch.

Note to self:
currently supported diagnostics format options for GCC:
