That's as may be. But it never occurred to me that this might be FUD (until you kindly pointed it out). Rather, I thought it was a curiosity about the way that gcc's code generation worked (and not *inherently* incorrect, so long as one didn't regard compiling without -O as "compiling"), and - more importantly - a hint as to how to avoid unnecessary pain (to me, as a user of gcc, at that time, and still now). (After all, I'm still really a Linux lurker. Also, having lost most of yesterday trying to get Plan 9 to install on a new machine without destroying it's partition table (I tried 3 times before giving up and zeroing the disk), I'm not too well disposed to Plan9 right now. Although to be fair, it's working great now..... - BTW: What *does* "panic iunlock" mean (I think that was it), apart from "You're stuffed - go and hit your head on a nearby wall, and then start over..."? First time I thought it was because I had done something silly, but the second time I *hadn't* done the silly thing.... Still, at least the good side effect is that I no-longer have Windows on the machine :-) ) BTW: what's the Plan9 equivalent of Unix's "find . -name ... -print"? (always a good fallback for a beginner :-) Martin -- Martin C. Atkins martin@mca-ltd.com Mission Critical Applications Ltd, U.K.
