Hmm.

Obviously a build of a clean cvs checkout will work, since the built 
sources are included in it already.

What might fail is if you change packets.def and then recompile.  If it 
so happens that (for instance) packets.o is compiled before 
packets_gen.h, then the compilation may not be correct.  A second run of 
"make" would be required to fix it.
