Is there any book, manual, notes, etc. that contains a listing of all diagnostic messages with some description of their meanings. I'm dying here with the messaging and other than Google, have difficulty understanding some of them. My fault not yours. It would help to have a document. I've looked around at gcc.gnu.org and nothing pops out at me. Less we get into some odd state where someone says "the messages say what they mean" or the "message meaning is obvious", there is at least one loader message where this is not the case. A document would be helpful. art
