5# Warning flags for compiling the kernel and components of the kernel.
6#
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.

15# The following flags are next up for working on:
16#	-W
17#
18# When working on removing warnings from code, the `-Werror' flag should be
19# of material assistance.
