6400	gcc3.4.4(cygwin) code will not compile if macro BOOST_LCAST_NO_WCHAR_T is defined	grzechu81@…	nasonov	"Using compiler gcc 3.4.4 (cygwin) and boost 1.48.0
following code:

{{{
#include <boost/lexical_cast.hpp>
int main(int argc, char * argv[])
{
    return 0;
}
}}}

will result in compiler error:

{{{
.../boost_1_48_0/boost/lexical_cast.hpp: In function `bool boost::detail::parse_inf_nan_impl(const CharT*, const CharT*, T&, const CharT*, const CharT*, const CharT*, const CharT*, CharT, CharT)':

}}}


It is because if using this compiler, macro BOOST_NO_STD_WSTRING is defined , so.. lexical cast defines BOOST_LCAST_NO_WCHAR_T.

Some code is #ifdef'ed with this macro but not all that should. So there is discrepancy."	Bugs	closed	Boost 1.49.0	lexical_cast	Boost 1.48.0	Showstopper	fixed	gcc.3.4.4 cygwin BOOST_LCAST_NO_WCHAR_T	antoshkka@…
