them will expand to tokens that themselves are macros defined in terms

The problem is, "32_" is not a valid preprocessing token, and we don't

want extra underscores (e.g., "nlm_32_"). The NLM_XCAT2 macro will
47
cause the inner CAT2 macros to be evaluated first, producing

still-valid pp-tokens. Then the final concatenation can be done. */
