+   The NLM_CAT4 hack is to avoid a problem with some strict ANSI C
+   preprocessors.  The problem is, "32_" or "64_" are not a valid
+   preprocessing tokens, and we don't want extra underscores (e.g.,
+   "nlm_32_").  The XNLM_CAT2 macro will cause the inner NLM_CAT macros
+   to be evaluated first, producing still-valid pp-tokens.  Then the
+   final concatenation can be done.  (Sigh.)  */
