Subject: How to get rid of warning messages during kernel make?

I am trying to automate the building process for the kernel for my system. 
I am using a perl script to do the file modifications and using system calls
to do the make depend and make portions.  The problem is that I would 
like to not have any of the build information sent to the screen.  I have
set
the CWARNFLAGS to " " by the following in my perl script:

system("make CWARNFLAGS=\" \" depend >> logfile.log");
system("make CWARNFLAGS=\" \" >> logfile.log");

But I still get the following messages:

./aicasm: 446 instructions used
../../dev/dpt/dpt_control.c:389: warning: #warning "O/S Version
determination is an ugly hack"
../../pci/ncr.c:1486: warning: initialization discards `volatile' from
pointer target type
../../pci/ncr.c:1486: warning: initialization discards `volatile' from
pointer target type
../../dev/dpt/dpt_control.c:389: warning: #warning "O/S Version

../../i386/isa/seagate.c: In function `sea_data_output':
../../i386/isa/seagate.c:1111: warning: assignment discards `volatile' from
pointer target type
../../i386/isa/seagate.c: In function `sea_data_input':
../../i386/isa/seagate.c:1181: warning: assignment discards `volatile' from
pointer target type

What is the best way I can prevent these messages from being printed to the
screen?

  Thanks, 
      Chris
