wpa_supplicant compile against madwifi-ng error

[Eugene de Grave]

I'm trying to compile wpa_supplicant-0.5.2 against the latest snv 
madwifi-ng (1508). Wpa_supplicant-0.5.1 compiles just fine with this 
.config file:

CONFIG_WIRELESS_EXTENSION=y
CONFIG_DRIVER_MADWIFI=y
CFLAGS += -I/root/wifi/madwifi-ng
CONFIG_CTRL_IFACE=y

For some reason version 0.5.2 errors with (last part of compile):

What could be the reason for this compile error? The .config file seems 
short to others I found but it's all I seem to need.
