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

# Note that the newly added -Wcast-qual is responsible for generating
|

# most of the remaining warnings. Warnings introduced with -Wall will
|
|
# also pop up, but are easier to fix.

# On the alpha, make sure that we don't use floating-point registers and
