+/* The <ansi.h> header attempts to decide whether the compiler has enough
+ * conformance to Standard C for Minix to take advantage of.  If so, the
+ * symbol _ANSI is defined (as 31415).  Otherwise _ANSI is not defined
+ * here, but it may be defined by applications that want to bend the rules.
+ * The magic number in the definition is to inhibit unnecessary bending
+ * of the rules.  (For consistency with the new '#ifdef _ANSI" tests in
+ * the headers, _ANSI should really be defined as nothing, but that would
+ * break many library routines that use "#if _ANSI".)
+
+ * If _ANSI ends up being defined, a macro
+ *
+ *	_PROTOTYPE(function, params)
+ *
+ * is defined.  This macro expands in different ways, generating either
+ * ANSI Standard C prototypes or old-style K&R (Kernighan & Ritchie)
+ * prototypes, as needed.  Finally, some programs use _CONST, _VOIDSTAR etc
+ * in such a way that they are portable over both ANSI and K&R compilers.
+ * The appropriate macros are defined here.
