Great piece of detective work Milton. The good news is that this has already been done in the 1.4.x tree and nobody has reported any problems without the pragmas. I'll leave it to Jean-Marc to decide what to do about this in the 1.3.x tree. > It appears that gcc mishandles some #pragma statements on some > platforms.

Apparently it doesn't handle weak symbols and so at link time cannot handle static member variables in class templates. -- Angus
