Sorry, I should have answered more clearly.  System headers are of 
course written in C, but usually portably enough to allow them to be 
included in either C or C++ programs.  But this syntax

was not part of C when C++ was invented, and it isn't valid C++.

What best to do about it, I'm not sure.  We could work around it in 
Rosegarden by adding a separate C file just to define the mutexes in.  
Maybe there's another usual workaround.  Where does one get this 
header from?  Is there NPTL-specific documentation?  Can you find out 
why it uses such a recent C extension and whether there's an expected 
way to use it from C++?
