dnl Most compilers print some kind of a version string with some command
dnl line options (often "-V"). The version string should be checked
dnl before doing a test compilation run with compiler-specific flags.
dnl This is because some compilers (like the Cray compiler) only
dnl produce a warning message for unknown flags instead of returning
dnl an error, resulting in a false positive. Also, compilers may do
dnl erratic things when invoked with flags meant for a different
dnl compiler.
