Oh, I think I missed answering the simple question here.  Thusly:

  #include "valgrind.h"

  bool running_under_valgrind (void)
     return (RUNNING_ON_VALGRIND) ? true : false;

Is that what you want, or did you mean something different?

You might want to cache the result of RUNNING_ON_VALGRIND
so that the common (production) case overhead is reduced to
a load and conditional branch, rather than the strange sequence
of stores and rotates generated by the macro.
