Should try_compile() be used with CMake to test whether particular compiler options are supported by the C compiler, just as the autoconf script uses AC_COMPILE_IFELSE? (Sadly, it appears that CMake would require that the test program be in a file of its own, rather than letting you embed it in the script, as autoconf does.)
