[C++-sig] Re: [boost] function/function_template.hpp

[David Abrahams]

BTW, this wasn't a vc7-specific error. I don't know how anyone missed
seeing it with msvc6; maybe it only get stimulated by the Python library.

In any case, I've checked in this patch as a workaround until Doug can look
at it more closely:

*** function_template.hpp.~1.41.~ Sun Jul 21 00:48:07 2002
--- function_template.hpp Sun Jul 21 06:59:15 2002
***************

      }

      // Assignment from another BOOST_FUNCTION_FUNCTION
!     void set(const BOOST_FUNCTION_FUNCTION& f,
!              int deprecated = 0)
      {
        if (&f == this)
          return;

--- 339,347 ----
      }

      // Assignment from another BOOST_FUNCTION_FUNCTION
!     void set(const BOOST_FUNCTION_FUNCTION& f)
      {
+       int deprecated;
        if (&f == this)
          return;
