This _particular_ failure is expected (you aren't showing enough of the
config.log output).  Remember, to determine if something is a type vs.
an expression, autoconf performs TWO compilation tests, and relies on
the fact that sizeof(expr) and sizeof((expr)) both compile, but
sizeof(type) compiles while sizeof((type)) must fail.  The back-to-back
compilation is necessary to ensure that something being probed for is a
type name rather than an arbitray expression.

So just because _some_ tests fail (as expected) does not mean that this
particular failure is where configure is messing up.
