Recognize Clang to be a GCC-compatible compiler Clang aims to be compatible with GCC when it comes to command-line parameters. Where we enable functionality based on the presence of a GCC-compiler, we can use the same functionality with Clang. This patch introduces a new variable CXX_COMPAT_GCC which is true if the compiler handles the same options as GCC, and this variable is subsequently used in tests instead of CMAKE_COMPILER_IS_GNUCXX (which remains if we need to test if we really have GCC, e.g. for version) 2013-08-06 15:43:35 -05:00			`include (UseCompVer)`
