+ * it will be easy to apply any patches that may be distributed.
+ *
+ * The general idea is that systems conforming to the various standards
+ * should need to do the least amount of changing. Definining the various
+ * items in ths file usually means that your system is missing that
+ * particular feature.
+ *
+ * The order of preference in standard conformance is ANSI C, POSIX,
+ * and the SVID.
+ *
+ * If you have no clue as to what's going on with your system, try
+ * compiling gawk without editing this file and see what shows up
+ * missing in the link stage. From there, you can probably figure out
+ * which defines to turn on.
