Apply patch from Stuart Hickinbottom <stuarth@hickinbottom.demon.co.uk> to fix complication problems with gcc 4.1.1 where configure didn't detect LLONG_MAX properly. Fix by removing configure check completely, and using STL interface.

-dnl @synopsis AX_CHECK_LLONG_MINMAX
-dnl
-dnl This macro will fix up LLONG_MIN and LLONG_MAX as appropriate. I'm finding

-dnl seems to have gone quite mad.
