lexical_cast is using math::changesign with long double regardless of whether BOOST_MATH_NO_LONG_DOUBLE_MATH_FUNCTIONS is defined or not. This is causing Boost.Test build problems (see here http://tinyurl.com/af5453h ).
I'm pretty sure this is a bug in lexical_cast, so I've opened a ticket: https://svn.boost.org/trac/boost/ticket/8162
So, portable way of changing sign is just to multiply on -1 ? And math::isnan I shall change to value != value ? And math::isinf to something like value >= numeric_limits<>::max? But why don't we do that in Boost.Math?
I've assigned it to the last person to touch lexical_cast.hpp. Apologies if that's not right. There is no entry for lexical_cast in libs/maintainers.txt.
You've assigned it to the right person, Antony has become the new maintainer of lexical_cast as per http://lists.boost.org/Archives/boost/2011/05/181523.php. This is also reflected in https://svn.boost.org/trac/boost/report/15 and should probably be added to libs/maintainers.txt.
I'll commit changes to libs/maintainers.txt today. -- Best regards, Antony Polukhin
