Hi Randolph,

Well I reach to compile gcc-3.1.1 without error (xc toolchain hppa -> 
hppa as gcc bootstrap).

Now I compile kernel 2.4.18-pa54 (last cvs I got Friday morning) for 
32-bits config first (not 64-bits yet) and may be that is why I do not 
met the problem mentioned below

OTC I met a strange problem with modules:

find kernel -path '*/pcmcia/*' -name '*.o' | xargs -i -r ln -sf ../{} pcmcia
if [ -r System.map ]; then /sbin/depmod -ae -F System.map  2.4.18-pa54; fi
depmod: *** Unresolved symbols in 
/lib/modules/2.4.18-pa54/kernel/drivers/input/input.o
depmod:         mod_timer_R1f13d309
depmod:         unregister_chrdev_Rc192d491
depmod:         printk_Rdd132261
depmod:         jiffies_R0da02d67
depmod:         del_timer_Rfc62f16d
depmod:         register_chrdev_Rddc3984b
depmod:         sprintf_R1d26aa98
depmod:         try_inc_mod_count_R133c9d8f
depmod: *** Unresolved symbols in 
/lib/modules/2.4.18-pa54/kernel/drivers/input/keybdev.o
depmod:         kmalloc_R93d4cfe6
...

Any idea?

Thanks again for help and advises,
	Joel

PS: I join my compile log just in case you notice other details
