Preprocess output is fine. The problem lies in how gcc 2.95.3 handles
inlined member functions. Obviously they are automaticly 'inline extern'
so if the function can't be inlined there is still no code generated.
With the standard gcc 2.95.3 this was not a problem because it
always respects the inline directive. SuSEs gcc is a bit more picky
and refuses to inline some functions because they are too big.
I might find a way to tweak SuSE to produce correct code but I'm
afraid we will run again into this problem sooner or later
with another distribution.
David, I strongly recommend that you install a newer complier
preferably gcc 3.2.x. (There are still some open issues with
gcc 3.3 in L4 userland.) The kernel without inlined code is not
really tested and you soon might run into problems with kernel
