David Malcolm <dmalcolm at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|ASSIGNED |RESOLVED Resolution|--- |FIXED --- Comment #4 from David Malcolm <dmalcolm at gcc dot gnu.org> --- More recent gcc (e.g. today's) is saner: $ gcc -help gcc: error: unrecognized command line option ‘-h’ gcc: fatal error: no input files compilation terminated. In particular, it doesn't print the bogus suggestion, presumably due to r242965. Closing this one out.
