A general thing - without this then:

 Your std lib is not thread safe.
 Your C lib is not thread safe.
 g++ will not emit thread safe exception handling code.

Thus while for C programs enabling thread support is just a question of
linking to the right libraries, for C++ you also need to ensure that the
compiler "knows" that you want thread safe code.
