Argument promotion fails dependent libs on platforms not supporting long double

[boost.lists@…]

The following code fails to compile on FreeBSD 9.1, gcc 4.2.1:

#include <boost/spirit/include/karma.hpp>

#include <string> #include <iterator>

int main() {

using namespace boost::spirit::karma; std::string result; std::back_insert_iterator sink(result); unsigned short a; generate(sink, auto_, a);

}

(In [85188]) Made a few core functions usable with long double even when there is no std lib long double support. Fixes #8940.
