However, it didn't work for me.

First off, why are you trying to /set/ a value that is (or should be)
supplied to you by your C implementation? Are you just trying to
second-guess your compiler, or are you trying to change the limit that
the compiler imposes. FWIW, that manifest constant is (or should be)
defined by the compiler, and externalized for your information only.

Secondly, what do you mean by "it didn't work for me". What did you get?
What did you expect to get? How did the #define fail you?
