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

[Daiki Ueno]

Follow-up Comment #3, bug #43970 (project gettext):

Consider the following code:

++++
#include <stdio.h>
#define R "foo"
void foo (void) { printf ("%s\n", gettext (R"aaa(\u3042")); }
int main (void) { foo (); return 0; }
----

This is a valid pre-11 code which passes a string "fooaaa(あ" to gettext, but
invalid as C++11.  If xgettext treated the code as C++11, it couldn't detect
the error until EOF is read.

> 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?

Yes, if that is possible, it would be a desired behavior.
