Does the header defining this macro get included implicitly from the 
command line?  If not, you need to include appropriate headers before 
testing it....  (It might be a good idea, before doing anything more based 
on such macros, to do a preparatory patch series converting them to 0/1 
form with #if used, instead of undefined/defined with #ifdef, so that 
-Werror -Wundef detects any cases where required headers are not 
included.)
