//  MACRO:         BOOST_NO_STDC_NAMESPACE
//  TITLE:         std:: namespace for C API's
//  DESCRIPTION:   The contents of C++ standard headers for C library
//                 functions (the <c...> headers) have not been placed
//                 in namespace std.  This test is difficult - some libraries
//                 "fake" the std C functions by adding using declarations
//                 to import them into namespace std, unfortunately they don't
//                 necessarily catch all of them...
