(I assume 'npose' is a typo for 'npos')

I'm unsure whether this would be the right thing to do here. If you 
define npos like above, it will result in a 32 bit value. When used 
together with 64 bit values (size_t), this is IMHO a potential source of 
bugs - although I don't have evidence.

Have you considered/tried

   static const size_t npos = -1;

or optionally (if npos_type is needed):

   typedef size_t npos_type;
   static const npos_type npos = -1;

? This should (AFAICS) provide the "correct" 64 bit value you are 
looking for.
