Sacado_cmath.hpp: Change_preprocessor_directive
Created by: sebrowne
Eliminate preprocessor directive by moving the two "defined" directives into the statement in which they are used.
This allows for Trilinos to build on Windows (packages required for Xyce) with Intel and the Intel MKL.
Intel throws a warning about "defined" is always false in a macro expansion in Microsoft mode. This macro appears to only be used in this file, so I simply moved the macro into the statement in which it is used.
