C++ member function pointers in ISO C++

[Terry Barnaby]

We are trying to compile some library code that passes the address of an
objects member
function together with the objects address to be used in a call-back
method. Having upgraded
to GCC 2.96 we now get a compilation error " ISO C++ forbids taking the
address of a
non-static member  function to form a pointer to member function.  Say
`&A::Func1'"

Questions:
1. Is there a proper way in ISO C++ of passing and storing a pointer to
a member function ?
2. Is there a compiler switch or other mechanism to allow the previous
GCC behaviour ?

Cheers

Terry
