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