[Boost-users] Boost 1.42 TR1 With GCC 4.5 selects wrong overload

I am using the portable style boost headers for tr1 implementation from Boost 1.42 such as #include When i use gcc implementation of tr1 (Mingw GCC 4.5.1 from TDM, BOOST_HAS_GCC_TR1 defined) everything works fine. However when i select boost tr1 implementation (i.e not define the above macro) some stdlib functions such as std::abs gets wrong overloaded selected. For. e.g. in gcc/tr1 std::abs((signed char)5) returns an int while in boost/tr1 it returns a double. A compilable example is like #include <cstdlib> #include <iostream> #include <typeinfo> #include int main(){ std::cout<
