Maybe I'm misreading what you said, but I don't find it mindboggling that an application would have default settings for certain options. That's basically what we're talking about here. If a warning can be either on or off, then one of these two has to be a default for that exact situation when the user does just say "gcc" and doesn't specify whether they want the warning or not. A number of distros change the defaults of gcc in order to produce more warnings, as some can point to real security issues. This runs afoul of HotSpot's use of -Werror which presumably assumes the default set of warnings used by a certain version of gcc. I think the appropriate solution to this is, as Andrew suggests, to make explicit our preference for that warning rather than relying on the implicit defaults. > -- > Erik Trimble > Java System Support > Mailstop: usca22-123 > Phone: x17195 > Santa Clara, CA > Timezone: US/Pacific (GMT-0800) > -- Andrew :) Free Java Software Engineer Red Hat, Inc.
