* 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
* The order of preference in standard conformance is ANSI C, POSIX,
* 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.

/* Miscellanious features */
/**************************/
* Check your /usr/include/sys/stat.h file. If the stat structure
* does not have a member named st_blksize, define this. (This will
* most likely be the case on most System V systems prior to V.4.)
/* #define BLKSIZE_MISSING 1 */
* The return type of the routines passed to the signal function.
* Modern systems use `void', older systems use `int'.
* If left undefined, it will default to void.
/* #define SIGTYPE int */
* If your system has no typedef for size_t, define this to get a default
/* #define SIZE_T_MISSING 1 */
* If your machine uses unsigned characters (IBM RT and RS/6000 and others)
* then define this for use in regex.c
/* #define CHAR_UNSIGNED 1 */
* Check in your /usr/include/setjmp.h file. If there are routines
* there named _setjmp and _longjmp, then you should define this.
* Typically only systems derived from Berkeley Unix have this.

/* Missing library subroutines or system calls */
/***********************************************/
* These three routines are for manipulating blocks of memory. Most
* likely they will either all three be present or all three be missing,
* so they're grouped together.
/* #define MEMCMP_MISSING 1 */
/* #define MEMCPY_MISSING 1 */
/* #define MEMSET_MISSING 1 */
* Your system does not have the random(3) suite of random number
* generating routines. These are different than the old rand(3)
/* #define RANDOM_MISSING 1 */
* Your system does not have the strcasemp() and strncasecmp()
* routines that originated in Berkeley Unix.
/* #define STRCASE_MISSING 1 */
* Your system does not have the strchr() and strrchr() functions.
/* #define STRCHR_MISSING 1 */
* Your system lacks the ANSI C strerror() routine for returning the
* strings associated with errno values.
/* #define STRERROR_MISSING 1 */
* Your system does not have the strtod() routine for converting
* strings to double precision floating point values.
/* #define STRTOD_MISSING 1 */
* Your system lacks the ANSI C strftime() routine for formatting
* broken down time values.
/* #define STRFTIME_MISSING 1 */
* If you have a 4.2 BSD vintage system, then the strftime() routine
* supplied in the missing directory won't be enough, because it relies on the
* tzset() routine from System V / Posix. Fortunately, there is an
* emulation for tzset() too that should do the trick. If you don't
* have tzset(), define this.
/* #define TZSET_MISSING 1 */
* Some systems do not support the external variables tzname and daylight.
* If this is the case *and* strftime() is missing, define this.
/* #define TZNAME_MISSING 1 */
* If your system does have ANSI compliant header files that
* provide prototypes for library routines, then define this.
* If your compiler define's __STDC__ but does not support token
* pasting (tok##tok), then define this.
/* #define NO_TOKEN_PASTING 1 */

/* Much of this is (still, unfortunately) black magic in nature. */
/* You may have to use some or all of these together to get gawk */
/*****************************************************************/
* Look in your /usr/include/stdio.h file. If the return type of the
* sprintf() function is NOT `int', define this.
/* #define NON_STD_SPRINTF 1 */
* Define this if your system lacks vprintf() and the other routines
* that go with it. This will trigger an attempt to use _doprnt().
* If you don't have that, this attempt will fail and you are on your own.
/* #define VPRINTF_MISSING 1 */
* Casts from size_t to int and back. These will become unnecessary
* at some point in the future, but for now are required where the
* two types are a different representation.
* Define this if your library does not provide a system function
* or you are not entirely happy with it and would rather use
* a provided replacement (atari only).
/* #define SYSTEM_MISSING 1 */
* Define this if your system lacks the fmod() function and modf() will
