That's because the message is too terse. Not even quotes around
'end of file'.

But you would agree with me that

    foo.y:2.1: erreur: frontière de fichier inattendu

would be grammatically incorrect and thereby give an entirely
wrong meaning to the sentence.

Why would this be unacceptable to translators?
YYCASE_(0, YY_("syntax error."));
YYCASE_(1, YY_("syntax error.\nunexpected token: '%s'"));
YYCASE_(2, YY_("syntax error.\nunexpected token: '%s'\nExpected token: '%s'"));
YYCASE_(3, YY_("syntax error.\nunexpected token: '%s'\nExpected token: '%s' or '%s'"));
YYCASE_(4, YY_("syntax error.\nunexpected token: '%s'\nExpected token: '%s' or '%s' or '%s'"));
YYCASE_(5, YY_("syntax error.\nunexpected token: '%s'\nExpected token: '%s' or '%s' or '%s' or '%s'"));

Why not? Unlike the other half-"solutions", this one works for all
languages.

You already put additional information about the errors in 'note:' lines;
why would you insist that the "unexpected token" info and the "expected
tokens" info would be on the same line, in the same sentence?
