I note in comeau.hpp:

# if defined(_MSC_VER) && _MSC_VER <= 1300 # define BOOST_NO_STDC_NAMESPACE ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ # if _MSC_VER > 100 // only set this in non-strict mode: # define BOOST_NO_ARGUMENT_DEPENDENT_LOOKUP # endif # endif

The indicated line seems completely out-of-place here - it's a library thing, not a compiler thing, and it breaks builds with my compiler. I'm deleting it and checking in. Please let me know if you disagree with this move.

It's probably a commeau version thing - I think commeau used to use the same library headers as VC++, but now provides it's own? John.
