Bug#638239: pd-mjlib: FTBFS on hurd & kfreebsd

[Hans-Christoph Steiner]

This is fixed upstream already in most of these, and will be soon in  
the rest.  Its less than half of the pd-* packages that are effected,  
according to buildd.  The list of affected packages is:

pd-bsaylor pd-cxc pd-cyclone pd-ekext pd-ext13 pd-ggee pd-hcs pd- 
markex pd-maxlib pd-mjlib pd-moonlib pd-pddp pd-sigpack pd-smlib pd- 
windowing
