Hmm. Did you try marking you template functions inline? template functions 
aren't neccesarily inlined _automatically_ with all versions of gcc.


I've got this: 
progtemp without inline 10.9 sec.

Then I tagged the _declarations_ inline: 

template <class T> class adouble {
   public:
      inline adouble();
      inline adouble(const T v);
      inline adouble(const T v1, const T v2);
      
      inline void operator = (const T v);
      inline void operator = (const adouble& v);
      
etc...

An I've got:
progtemp with inline 0.7 sec.
