Sorry, I don't understand.

Is the feature your trying to test related to the compiler, or to the
system?  If the language is relevant, then indeed AC_SYS is wrong.  If
the language is not, then I don't understand your sentence: all that
matters is whether we are running this system or not, to decide, for
instance, of the programs to compile.
