PROBLEM: laptop touchpad on linux-2.6.0-test4

PROBLEM: laptop touchpad on linux-2.6.0-test4

[Chris Peterson]

I upgraded a working Redhat 9 installation (linux-2.4.20) to
linux-2.6.0-test4. I can boot and start X and Gnome successfully.
Unfortunately, my laptop's touchpad and mouse "joystick" do not work. My
laptop is a Dell Latitude C400. I have not tried an external mouse because
my laptop does not have an external mouse port.

Using Google, I've found some LKML threads about problems with the Synaptics
touchpad driver and the evdev kernel module, but the threads end before a
verified solution ("it works now. thanks!") is posted. Is there a known fix
for this touchpad problem?

thanks,
chris

Please see:

driver and bunch for extra kernel patches needed to make track stick
work

Hmm, I downloaded gpm-1.20.1, unpacked it, applied the patches (tried
it both with the cumulative one and with the single ones), ran

autoconf && ./configure && make

and got:

[...]
gcc -I/usr/src/gpm/gpm-1.20.1/src -DHAVE_CONFIG_H -include
headers/config.h -Wall -DSYSCONFDIR="\"/usr/local/etc\""

Any ideas what I did wrong?

What GCC version? I think the problem is because of declaration after
statements which is allowed in newer standard. Please try the patch 
below, I will update the web page later tonight.
