Borland compiler, templates, wxWeakRef

[ATS]

I noted some discussions about problems with the Borland C++ compiling template
code and wxWeakRef. 

The problem seems to be that BCC cannot use any type or const expressions as
template arguments when specializing. 

For wxWeakRef, the workaround is to only use the static case also for Borland
(just as for VC6).  

I've made a patch along these lines. A new define: 

  HAVE_TEMPLATE_OVERLOAD_RESOLUTION 

was added to defs.h. 

That would make it possible to use with wxAUI again. Hope I have the full 
picture here.
