--- Comment #13 from Greg Chandler <chandleg at wizardsworks dot org> --- Created attachment 61590 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=61590&action=edit Ignores warnings that are routed to stderr, causing normal checks to fail This removes any false positives during the header and file checks when the compiler issues a warning that is not an actual error. The matching string is "error:" For example, on alpha systems the stack protector is not available for the platform, but because it can't be disabled at compile time, the -fstack-protector warning can not be suppressed, it can only be ignored after-the-fact.
