I don't know if it counts as a very persuasive data point, but a real large port of mine, octave, won't build under egcs (I got an internal compiler error for which I submitted a bug report). Gcc-2.8.1 compiled and ran it fine, which gcc-2.7.2.1 couldn't do (it could compile but not run it). Octave makes heavy use of templates, libstdc++, and virtual functions. Since our kernel hasn't any c++, it probably won't really matter, but I thought I'd put the data in your hands and let you decide. ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@glue.umd.edu | communications topic, C programming, and Unix. 213 Lakeside Drive Apt T-1 | Greenbelt, MD 20770 | I run Journey2 and picnic (FreeBSD-current) (301) 220-2114 | and jaunt (NetBSD). ----------------------------+----------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
