cmake should test for ansi stream header files
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
CMake should be used to test for ansi header files. Right now, it uses them for gcc and devenv but users can turn on VTK_USE_ANSI_STDLIB by hand and break code. The HP supports ANSI, but does not have the new header files. This should be a cmake test.
