One of the regression tests for gcc is to compile *a* Linux kernel, although I have no clue which kernel they use, or if they just haul down the latest one from the Internet.

I haven't seen it on RH 7.x; I had to download and install it separately. And it is a *royal* pain to get all the symbols/paths/libraries, etc., correct if you want to use *anything* other than the default compiler/libraries/binutils with Red Hat. One would need extreme motivation and extreme care.
For you (fellow) Athlon geeks, 2.95.x generates better code than either 2.96.x or 3.0.x on the Atlas high-speed numerical linear algebra library. The reverse is true for IA64; 3.0.x is about the only thing that generates decent code. If that's motivating enough, have at it. YMMV. -- znmeb@aracnet.com (M.
