Compile Warnings on Ubuntu 5.04

[gyoza at comcast.net]

I get the following warning when I compile the CVS version (2005-09-17)
of the madwifi driver:

Warning: could not find /home/gyoza/madwifi/ath_hal/.hal.o.cmd for
/home/gyoza/madwifi/ath_hal/hal.o

Below is exactly what I did up to that point:

-- fresh install of Ubuntu 5.04
-- removed the "linux-restricted-modules" package, which includes an
older version of madwifi
-- updated the entire system
-- installed "linux-headers" 2.6.10-5-386
-- installed "sharutils"
-- installed "CVS"
-- installed "gcc" 3.3.5
-- downloaded madwifi with the following command: "cvs -z3
-d:pserver:anonymous at cvs.sourceforge.net:/cvsroot/madwifi co madwifi"
-- rebooted
-- cd madwifi
-- make clean
-- make all 2>errors.log

The questions are, why do I get those warnings and are they serious
enough to prevent the driver from functioning properly?

(In the past I had tried installing the driver.  The modules install to
the wrong location.  After making corrections, the driver will load and
work with kismet, but the card almost never makes a connection to the
access point.  Before addressing those issue, I figure I should examine
the compile warnings.)
