Update of /cvsroot/CMake/CMake/Tests/TryCompile
In directory public:/mounts/ram/cvs-serv8323/Tests/TryCompile

Modified Files:
	CMakeLists.txt 
Log Message:
Fix CHECK_(C|CXX)_COMPILER_FLAG macro test

The flag "-_this_is_not_a_flag_" was not rejected by GCC 4.0 on older
Mac OS X.  We now use "---_this_is_not_a_flag_" instead, which will
hopefully be rejected by all compilers.
