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