It does define std::numeric_limits<T>. Something more subtle must be wrong.

If I preprocess and compile like this ...

% cxx -E -std strict_ansi -tlocal -Iboost include_lcast_precision.cpp | grep -v '^#line ' > z_pp.cpp
% cxx -c -std strict_ansi -tlocal z_pp.cpp

I get the error below. Does this give a clue?

More observations:
  - cxx 6.5 = EDG 245
  - cxx 7.1 = EDG 304
  - We also have MIPSpro 7.41 = EDG 245, which doesn't have a problem (but boost.config may work around it in some way...?).
