New build questions

[Jonathan Gibbons]

Does the new build automatically keep a copy of the build log?  If not, 
could it?    I don't always remember to use "make 2>&1 | tee build.log", 
so it would be nice if the build did it for me.

Could the new build report the number of warnings that occurred during 
the build? Simply "grep-ing" for the word "warning" (ignoring case) is 
usually a pretty good measure.

(For bonus points, if the build is being run from a suitable shell 
window with a suitable TERM type, could it use blinky red characters to 
report when the number of warnings has exceeded some preset maximum, 
such as the number of warnings in the most recent promoted build?)

Are there any other statistics that could usefully be reported at the 
end of build?  Could they be reported in a format that can easily be 
tracked over time by build systems such as Hudson or its alter egos?
