Compile statistics: 2.6.0-test5
Compiler: gcc 3.2.2
Script: http://developer.osdl.org/~cherry/compile/compregress.sh

Note: the numbers look drastically better, but this is skewed
      by the fact that CONFIG_CLEAN_COMPILE is now the default
      for defconfig and allmodconfig.

bzImage allmodconfig show 0 warning, but there seem to be
several "warning:" lines in the actual output.

Any chance you can add "bzImage (allyesconfig)"?

Cool stats, thanks.

Jeff,

I added allyesconfig to the stats.  Check out...
