6136,"Fix for ""variable set but not used"" warning with GCC >= 4.6",zeratul976@…,az_sw_dude,"GCC >= 4.6 gives the following ""variable set but not used"" warnings for code in boost/date_time/format_date_parser.hpp:

{{{
../../lib/boost/boost/date_time/format_date_parser.hpp:479:11: warning:
    variable 'current_char' set but not used [-Wunused-but-set-variable]
../../lib/boost/boost/date_time/format_date_parser.hpp:584:11: warning:
    variable 'current_char' set but not used [-Wunused-but-set-variable]
../../lib/boost/boost/date_time/format_date_parser.hpp:677:11: warning:
    variable 'current_char' set but not used [-Wunused-but-set-variable]
}}}

The warnings are triggered by any code that instantiates the format_date_parser class, for example:

{{{
#include <sstream>
#include <boost/date_time/posix_time/posix_time.hpp>

int main()
{
    std::stringstream ss;
    boost::posix_time::ptime p;
    ss >> p;
}
}}}

Looking at the code, I can see that the 'current_char' variable is indeed set but never used in those functions.

The attached patch fixes the warnings by removing the 'current_char' variable from those functions.",Patches,closed,To Be Determined,date_time,Boost 1.54.0,Problem,fixed,,
