problem with shared_ptr on CC v5.1

[wajr]

Unable to compile smart_ptr_test.cpp using Sun 
Workshop 6 2000/04/07 C++ 5.1 due to the following 
error:

"[snip...]/boost/smart_ptr.hpp", line 150: 
Error: "explicit" is not allowed here.

It seems that the explicit keyword may not appear on a 
templatized ctor for this compiler build. When the 
explicit keyword on line 150 is removed, the smart_ptr 
tests compile (and work) fine.

Note that smart_ptr_test.cpp compiles nicely with Sun
Workshop 6u1 C++ 5.2 (see the regression test results).
Please consider upgrading the compiler.

Boost focuses on the most recent versions of vendor's
compilers.   Nonetheless, we do appreciate your suggested
fix, but it's up to the maintainer whether the fix will be
integrated.
