Update of /cvsroot/CMake/CMake/Tests/PolicyScope
In directory public:/mounts/ram/cvs-serv2388/Tests/PolicyScope
Added Files:
CMakeLists.txt main.c
Log Message:
ENH: Better policies for functions and macros
This teaches functions and macros to use policies recorded at creation
time when they are invoked. It restores the policies as a weak policy
stack entry so that any policies set by a function escape to its caller
as before.
