[Anders Logg <logg@xxxxxxxxx>]

This is all caused by the pow() functions in real.h which have been
added since GMP types do not work with std::pow().

This does not give me any problems (g++ 4.2.3) so it's difficult for
me to debug. Let me know which compiler you are using so I can
reproduce the bug. (Or even better help me fix it...)
