We currently have BOOST_NO_EXPLICIT_FUNCTION_TEMPLATE_ARGUMENTS which is set
for that defect - though it's not really well named.

Not a bad idea if you want to add it to config/suffix.hpp:
#ifndef BOOST_NO_EXPLICIT_FUNCTION_TEMPLATE_ARGUMENTS
# define BOOST_DUMMY_DEFAULT_ARGUMENT(t)
#else
# define BOOST_DUMMY_DEFAULT_ARGUMENT(t) t* = 0
#endif
As long as the authors of those libraries are prepared to use it and make
the necessary changes...
John.
