This is a general behavioral change in gcc.

It has been recommended to link c++-applications with g++ for several
years (Approximately since the egcs day), but using gcc to link c++ has
continued to work, more or less at random, on some targets.

Nowadays you are supposed to apply g++, because linking c++ with gcc
already doesn't work on some targets and will almost 100% certainly stop
working in future releases of gcc.
