I had a few problems compiling Denx RTAI for ppc with gcc 3.3.2. Attached
patches seem to fix this - at least the examples run on my MPC5200. Changes
still compile ok on 2.95.4.

For linuxppc_devel patched with
patch-denx-linuxppc_2_4_devel-LABEL_2003_12_22_1500-ltt:

Change formatting of __asm__ in ltt_clear_bit to be similar to ltt_set_bit
to fix compile error.

For rtai-24.1.12-denx.tar.bz2:

Fix clobber list to fix compile error on gcc 3.3.2.
