  I don't like it (but I don't decide).

What don't you like?  What ought to change?

  However, having a test in gmpxx that 
  checks whether the version of gmp.h included matches and outputs a warning 
  (not an error, there can always be good reasons to do strange things) 
  otherwise would help diagnose this kind of issue.
  
That's a good idea.
