c-family: Have -Wformat-diag accept "decl-specifier" [PR103758]
I'm tired of seeing
cp/parser.c:15923:55: warning: misspelled term 'decl' in format; use 'declaration' instead [-Wformat-diag]
cp/parser.c:15925:57: warning: misspelled term 'decl' in format; use 'declaration' instead [-Wformat-diag]
every time I compile cp/parser.c, which happens...a lot. I'd like my
compilation to be free of warnings, otherwise I'm going to miss some
important ones.
"decl-specifiers" is a C++ grammar term; it is not actual code, so
should not be wrapped with %< %>. I hope we can accept it as an exception
in check_tokens.
It was surrounded by %< %> in cp_parser_decl_specifier_seq, so fix that.
In passing, fix a misspelling in missspellings.
PR c++/103758
gcc/c-family/ChangeLog:
* c-format.c (check_tokens): Accept "decl-specifier*".
gcc/cp/ChangeLog:
* parser.c (cp_parser_decl_specifier_seq): Replace %<decl-specifier%>
with %qD.
gcc/testsuite/ChangeLog:
* g++.dg/cpp0x/constexpr-condition.C: Adjust dg-error.
