       for MSVC only

1.11 (23 Apr 2002)

     - converted to use of CGAL_NTS gcd function 

1.4 (22 Mar 2002)

     - Changed conditional compilation for _MSC_VER to 
       _MSC_VER <= 1200 (i.e. VC6). We'll try to get the general
       design to work with VC7.

1.3 (19 Mar 2002)

     - PM_overlayer.h: changed use of Partition to Union_find.

1.2 (19 Mar 2002)

     - include/CGAL/HalfedgeDS_default_MSC.h: Fixed bug in copy
       constructor and assignment operator to copy pairs instead of

       original HalfedgeDS 3.4 (15 Jun 2001).
     - include/CGAL/HalfedgeDS_default_MSC.h: Added use of 
       CGAL_ALLOCATOR, otherwise the default allocator used in
       In_place_list that could be incompatible with new/delete
       would have created problems.

0.9 (9 Sept 2000)
