We're busy fixing compiler and platform specific issues, in preparation for
a 1.35 release. BTW that means that the version in SVN Trunk has *slightly*
more fixes in it than the sandbox version - which will be used for ongoing

I don't know, it works OK with Sun 5.9 on Linux (the only version of the sun
compiler I have access to), and the definition for that function is
certainly present in the header.

It's not helped by the Sun regression tests being stalled for the last
couple of weeks either :-(

The function is defined like this:

template <>
inline int
   return tools::digits<long double>();

Does this ring any bells as something that's problematic on that compiler?
How about if the inline specifier is removed?

HTH, John.
