* 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

|

|
* 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

|
