gcc7-pr77569.patch

Actually, the cb.error callback receives the message translated, without
further modifications like expansion of %s etc., so if we just don't strstr for
a substring, but instead strcmp with the whole message (after translation), I
think it should work both in C/locales without translation for this message as
well as locales that have it translated.  As my iconv handles ebcdic correctly,
I can't test though...
