Subject [jira] Commented: (STDCXX-157) [XLC++ 7.0, 8.0] explicit instantiation fails to emit some symbols
Date Wed, 15 Mar 2006 03:09:39 GMT
    [ http://issues.apache.org/jira/browse/STDCXX-157?page=comments#action_12370451 ] 

Martin Sebor commented on STDCXX-157:
-------------------------------------

Disabling the extern template extension (by #defining _RWSTD_NO_EXTERN_TEMPLATE) should do
it.
