clang in C++ mode accepts the compound initializer syntax
(TYPE) { VALUE... }
but — unlike gcc in C++ mode — requires that the values be constant
expressions.
As far as I can see, your patch will have the effect that
gettext (some_function_that_returns_a_string ())
will produce a syntax error in C++ mode.
Am I correct?
