There should be no problem in using the macro you suggested. The ARM
(chap 16.3.3), Preprocessing; rescanning and further replacement, reads:

   After all parameters in the replacement list have been replaced, the
   resulting list is rescanned for more macros to replace. If the name
   of the macro being replaced is found during this scan or during
   subsequent rescanning, it is not replaced.

Thus, there is no recursion involved. I have used this technique
successfully with g++ and dec-cxx. If you use g++, note that this
compiler uses non-standard syntax for the call to the overloaded
new-operator (curly braces instead of parentheses).
