Given that hello.c really is hello.c (....) I'd suspect``any'' program 
built with GCC>3.0+patch, uses libc and is staticly or dynamically 
linked doesn't run on a current kernel.

I'll give return0.c a go.

I'll find out.  I suspect not since I think the kernel is refusing to 
even load the program.
