USB support problem while compiling kernel

[Hamid <mylists@spils.com>]

Hi
I am trying to add Human Interface Device for USB support the kernel (2.4.20).
I should say that the USB support itself is working and it recognized my USB 
hubs and controllers. But when I want to add HID, it complians during "make 
bzImage". I have enabled "Input Core Support" both for keyboard and mouse.
And in USB support for HID, I am selecting "full HID support" and "Input Layer 
Support".
This is how it complains:
--------------------- Error Start ------------------------------------------

Any input is appreciated
Thanks
