/*
 * This file isolates configuration dependencies for gnu awk.
 * You should know something about your system, perhaps by having
 * a manual handy, when you edit this file.  You should copy config.h-dist
 * to config.h, and edit config.h.  Do not modify config.h-dist, so that
 * 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.
