Problem with compiling hostap-driver-0.1.1.tar.gz

I tried to compile hostap-driver-0.1.1.tar.gz on new SuSE 9.0 (kernel
2.4.21 with SuSE extensions) and got attached error message.
The problem is obviously that there is a problem with the HZ macro,
which has been changed in this kernel version (or in the according SuSE

I changed following two lines

static int ap_max_inactivity[MAX_PARM_DEVICES] = { AP_MAX_INACTIVITY / 


static int ap_max_inactivity[MAX_PARM_DEVICES] = { 300, DEF_INTS };

because AP_MAX_INACTIVITY is defined in hostap_ap.h as

#define AP_MAX_INACTIVITY (5 * 60 * HZ)

Afterwards compilation was completed sucessfully!
