  42  * This file uses ansi preprocessor features:
  43  *
  44  * 1.   #define mac(a) extra_ ## a     -->   mac(x) expands to extra_a
  45  * The old version of this is
  46  *      #define mac(a) extra_/.*.*./a
  47  * but this fails if the argument has spaces "mac ( x )"
  48  * (Ignore the dots above, I had to put them in to keep this a comment.)
  49  *
  50  * 2.   #define mac(a) #a             -->    mac(x) expands to "x"
  51  * The old version is
  52  *      #define mac(a) "a"
  53  *
  54  * For some reason, the 5.0 preprocessor isn't happy with the above usage.
  55  * For now, we're not using these ansi features.
  56  *
  57  * The reason is that "the 5.0 ANSI preprocessor" is built into the compiler
  58  * and is a tokenizing preprocessor. This means, when confronted by something
  59  * other than C token generation rules, strange things occur. In this case,
  60  * when confronted by an assembly file, it would turn the token ".globl" into
  61  * two tokens "." and "globl". For this reason, the traditional, non-ANSI
  62  * preprocessor is used on assembly files.
  63  *
  64  * It would be desirable to have a non-tokenizing cpp (accp?) to use for this.
