##### Set the compiler flags.

# This macro checks whether a compiler supports a compiler flag.

# If the flag is supported the flag will be added to the target compiler flags.
# GCC seems to be quite happy to accept flags it does not support when there is
# a `no' in it e.g. -Wno-not_supported_flag but will fail to compile with
# -Wnot_supported_flag. For that case all not-named parameters will be added to
# the target instead.
#
# param target                    The variable to add the compiler flag to.
# param flag                      The compiler flag to test.
# param variable                  The test macro needs a variable to store the
#                                 result of the test, this paramter holds that
#                                 variable.
# param ...                       If this variable is set it will be added to
#                                 target instead of flag when the compiler
#                                 supports flag.
