2378ba59e7 Fix for Borland compilers.
[SVN r39657]
2007-10-02 17:41:35 +00:00
53b95c386d Finalizes the fix to Bug #1260, making vtable_base an actual POD type (oops)
and playing more nicely with reinterpret_cast (thanks to Brad King for the
fixes).



[SVN r39285]
2007-09-14 21:05:46 +00:00
3312c7ffcd function_template.hpp:
- Pass-by-reference internally, when we can. Fixes #1067

de27ae9697 function/function_base.hpp, function/function_template.hpp:
- Switch from dynamic initialization of the vtable pointer to static
    initialization (Fixes #1260)
  - Handle member pointers properly, only using mem_fn within the invoker
    to deal with all of the messy bits of calling member pointers
