c-common.c contains
void c_parse_error (const char *msgid, enum cpp_ttype token, tree value)
which purports to format msgid, however, it contains things like,
error ("%s at end of input", string);
thus any magic %< in MSGID do not get munged. Resulting in,
error: expected %<,%> or %<...%> before '>' token
There needs to be a nesting mechanism to pass a format string as a % escape.
