[Boost-users] [Boost.LexicalCast] problem with 1.59 in Solaris

Trying to compile file libs/date_time/src/gregorian/greg_month.cpp I get an
error related to Boost.LexicalCast.

I have reduced the problem to a minimal test case:

#include <string>
#include <boost/lexical_cast.hpp>

void f(const char* s)
{
    std::string s1(boost::lexical_cast<std::string>(s));
}

My feeling is that this compiler has problems in the specializations for
boost::detail::is_stdstring and boost::detail::is_char_array_to_stdstring.

If I remove all those specializations the error goes away. I assume this is
not the perfect solution because I guess this will miss some optimization
of lexical_cast, but at least I can compile it this way  :(

Is there a better solution for this?
Has this problem been fixed in 1.60?
