Re: [Swarm-Support] Using Aqua tcl/tk on Mac OS X?

[Bill Northcott]

As far as I can see, the changes were introduced between Tcl/tk 8.3 and 
8.4.

In the tcl/tk sources these new const qualifiers are shown as the macro 
CONST84.  Tclconfig.sh always gives you the major and minor version 
numbers.  So it seems to me that it should not be too hard to incorporate 
CONST84 into tk extensions in the same way.

BLT 2.4z works happily with Tcl/tk 8.4, but would not work with 8.3.
