--- Comment #10 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Nicholas Williams from comment #7) > I think I have now attached everything. Under the "What we do not want" on > the bug reporting instructions, it says "An attached archive (tar, zip, > shar, whatever) containing all (or some) of the above." It also later says, > "Please avoid posting an archive (.tar, .shar or .zip)." However, the *.ii > files were nearly 3 megabytes and Bugzilla would not let me attach them. > Since the *.ii files were specifically requested in "What we need," I > compressed them into zip archives and attached them anyway. The .ii files aren't really needed here because you're not using any code that isn't fro mthe libstdc++ headers. We need preprocessed source when you're including your own headers or third party libs.
