Well, it is probably more of a change in gcc 3.3 than in the kernel.

Adding -fno-strict-aliasing (and keeping -Werror) got me through most of
the files. The only exceptions were:

nnpfs_vfsops.c 
nnpfs_node.c

Which complains about:

nnpfs_vfsops.c: In function `make_root_vnode':
nnpfs_vfsops.c:147: warning: use of cast expressions as lvalues is deprecated
nnpfs_vfsops.c: In function `nnpfs_read_super':
nnpfs_vfsops.c:217: warning: use of cast expressions as lvalues is deprecated


nnpfs_node.c: In function `nnpfs_iget':
