Clang rejects some simple BOOST_TEST() statements

[Tony Lewis <tonyelewis@…>]

Thanks again for the new BOOST_TEST() tool, which looks very useful.

Unfortunately, I'm unable to compile the following under clang++ (with or without -std=c++11) :

#define BOOST_TEST_MODULE comp_doub_mod

#include <boost/test/included/unit_test.hpp>

BOOST_AUTO_TEST_CASE( comp_doubs ) {
        const double num { 1.0 };
        BOOST_TEST( num == 1.0 );
        // BOOST_TEST( 1.0 == num );
}

This also fails if I swap to the commented-out BOOST_TEST() line.

The core of the error message is:

[...]/boost/test/tools/floating_point_comparison.hpp:259:25: error: 'mutable' cannot be applied to references
    mutable FPT         m_tested_rel_diff;
                        ^

I'll attach the full compiler error output.

thx for the report

Thanks for the successful fix in the develop branch. Will this make it into 1.60.0?
