boost header custom_time_zone.hpp triggers compile error

[Rudolf Leitgeb]

The file /usr/include/boost/date_time/local_time/custom_time_zone.hpp shipped with that package contains the statement

      return (dst_calc_rules_); //if calc_rule is set the tz has dst

in line 67. This line will not compile with the gcc shipped with Ubuntu Saucy Salamander. An informative discussion on this topic can be found here on stackoverflow: http://stackoverflow.com/questions/15234527/boost-1-53-local-date-time-compiler-error-with-std-c0x

The fix suggested in this page does indeed work.

I would therefore suggest that Ubuntu replace that line with the correct statement:

      return bool(dst_calc_rules_); //if calc_rule is set the tz has dst

This change imposes no measurable performance or other penalty and simply makes explicit what the compiler refuses to do implicitly.
