Kernel build

[Anthony du Casse]

I have optimised a GENERIC config file to optimise hardware device
configuration  for building FreeBSD OS 5.0 kernels.I recieve the following
message during the build process.

pes -Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual
-fformat-extensions -ansi -DKLD_MODULE -nostdinc -I-  -I. -I@ -I@/dev  -I/
../include  -mpreferred-stack-boundary=2  -c if_wi.c

I recieve approx 100 of these warnings for various source files.
 
What exactly does this message refer to, why and how could I solve it.

The kernel build is however successful, installs OK  and is operational. 

				Thanx
				Anthony.
