Thanks for addressing the problem.

(cvs diff -uN does contain bnew files, but patch does not know where to put
them, as it seems it rather believes the names in the -+ header than the
Index: one. But I have rather versions of diffutils and patch, so this might
have been addressed.)

Yes, I can. For now, I have a test for gcc 3.0.0/1 in the lib, and in case
gcc-3.0.0/1 is detected, I workaround by explicitly instantiating 
std::__cmath_power<double>. I'll deactivate for 3.0.1 and confirm that it
fails with some older sbnapshots and that it works with a new one.

I'll let you know in a few hours.
