[bug-gettext] [bug #43970] Incorrect "warning: unterminated string literal" for some C++11 raw strings

Follow-up Comment #2, bug #43970 (project gettext):

I'm not sure I follow - how could that possibly be valid C or pre-11 C++ code?
I think the syntax is intentionally such that it cannot be misinterpreted as
valid C.

this feature.

IMNSHO that would be a mistake, for two reasons:

1) C++11 *is* (modern) C++ and there will be more and more of it (and C++14
and C++17...). It doesn't make much sense to treat the current thing specially
and worse, make it non-default.

2) It would break extension-based detection of the language and make using
xgettext with the current/default version of C++ harder. That includes tools
on top of xgettext (e.g., selfishly, Poedit) that would have no reasonable way
of detecting C++11 use and would have to require user configuration for things
that should "just work".

Wouldn't it be better to loosen the warning instead? As far as I can tell, it
isn't causing any harm in this case - gettext-wrapped strings following after
such raw strings are still recognized by xgettext correctly, so it doesn't
seem to break the parser?
