/usr/local/obj/gcc/i686-pc-cygwin//libstdc++-v3/src/.libs/libstdc++.a(time.o): In function `_ZNSt11__timepunctIcE23_M_initialize_timepunctEPi':

/usr/local/obj/gcc/i686-pc-cygwin/libstdc++-v3/src/time.cc:54: multiple definition of `std::__timepunct<char>::_M_put_helper(char*, unsigned, char const*, tm const*) const'

collect2: ld returned 1 exit status
