preprocessor symbol map incorrect

I have this in my .emacs file:

=====.emacs=====
(semantic-c-add-preprocessor-symbol "UNIT_TESTS" "")
(semantic-c-add-preprocessor-symbol "SW_VERSION" "22"))
=====END .emacs=

This means semantic should be able to parse code that is within:

#if ( SW_VERSION >= 22 )
void someFunction( void ) { }
#endif /* ( SW_VERSION >= 22 ) */

and

#if defined( UNIT_TESTS )
void someOtherFunction( void ) { }
#endif /* defined( UNIT_TESTS ) */

And this works fine. However, in the case where I have a more complex check:

#if ( SW_VERSION >= 22 ) && ( defined( UNIT_TESTS ) )
void someOtherOtherFunc( void ) { }
#endif /* ( SW_VERSION >= 22 ) && ( defined( UNIT_TESTS ) ) */

This does not work.
