lex.c (_cpp_lex_direct): Use CPP_DL_NOTE instead of CPP_DL_PEDWARN...
* lex.c (_cpp_lex_direct): Use CPP_DL_NOTE instead of CPP_DL_PEDWARN,
CPP_DL_WARNING or CPP_DL_ERROR for note that diagnostics for C++ style
comments is reported only once per file and guard those calls on the
preceding cpp_error returning true.
* gcc.dg/cpp/pr61854-c90.c (foo): Expect a note, rather than error.
* gcc.dg/cpp/pr61854-c94.c (foo): Likewise.
* gcc.dg/cpp/pr61854-4.c (foo): Likewise.
* gcc.dg/cpp/pr61854-8.c: New test.
