I’m unsure if there’s a clean way to integrate this checking quirk in the configure script, since I’m not at all a huge fan of searching command line output like that: for all you know it might say something like "-Wno-string-plus-int is going to be the default sometime in the future" (like Apple LLVM has been known to say for -Wunused-command-line-argument, coincidentally), and grepping for specific error messages seems more finicky and/or prone to breakage than anything. I suppose this is best handled if we happen to come across such a problematic flag first: no need to optimise for cases that aren’t there yet. -S Download attachment "signature.asc" of type "application/pgp-signature" (802 bytes)
