[Bug runtime/4636] New: systemtap module generated kernel module does not compile on 2.6.21-1.3218.fc8 kernel

["wcohen at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

The C code that systemtap translator generates for the kernel does not compile
on stock rawhide 2.6.21-1.3218.fc8 kernel. Below is the result for attempting to
compile the simple add.stp test.
