5# Warning flags for compiling the kernel and components of the kernel.

7# Note that the newly added -Wcast-qual is responsible for generating
8# most of the remaining warnings.  Warnings introduced with -Wall will
9# also pop up, but are easier to fix.

19# When working on removing warnings from code, the `-Werror' flag should be
