/* --- BOOTSTRAPPING --- */
/* To bootstrap yourself onto a new system, you should modify this file \
appropriately. In most cases, you set a flag by saying ``#define \
FLAG''---i.e., you make a null definition. Don't set these flags to~0 \
or~1. However, in a few cases the macros are not flags and must be given \
the appropriate definition. */
/* --- MACHINE COMPILER FLAG --- */
/* This must be in lower case. Presently these are drawn from the list \
{ansi, bsd, dsu, ibmpc, mac, misc, mvs, sgi, sun, vax}. These \
flags may be used in #define statements within the source code to tailor \
things to a particular compiler or operating system. If you use \
./configure to generate custom.h, there will be no definition following \
this comment. */

``<*.h>'' are included near the beginning of each source file. The \
names of these files are standardized by ANSI. Unfortunately, not everyone \
has gotten around to ANSI yet. Therefore, here we include important files \
whose names may be nonstandard or whose functions may fluctuate. */

|realloc|, |strtod|, |strtol|. If it doesn't, either find the prototypes \
in another file and include it here, or actually give the prototypes here. */

supposed to define the |NULL| pointer, and the type |size_t|. Sometimes \
these are defined in other places as well. */

/* Other stuff handled by autoconf. */

here. But don't use it unless you have to. */

Microsoft, <malloc.h>; for Borland; <alloc.h>. Not necessary for ANSI; \
it's in <stdlib.h>. */

/* Numerical limits. We use the following ANSI macros: |INT_MAX|, \
|INT_MIN|, |LONG_MAX|, |LONG_MIN|, and |ULONG_MAX|, which are found in \
<limits.h>. If you can't find those macros, define the flag \
|HAVE_VALUES_H|, and possibly include another file with different names for \
the limits, such as <values.h> on the Sun. The flag |HAVE_VALUES_H| \
assumes that the macros |MAXINT| and |MAXLONG| are defined. If they are \
not, you must define them here. */

These were considered to be standard, but that might be a mistake. Those \
files are: <string.h>, <stdio.h>, <ctype.h>, <setjmp.h>, <time.h>. \
Remember that by convention these files should limit themselves to being \
included only once. Therefore, if for some reason you need to include one \
of these somewhere in this file, you should be able to do it without \
difficulty; the later automatic include just won't be done if those files \
are following standard protocol. */
/* (The flag |ANSI_CTYPE_H| is set automatically in config.h by ./configure.) */
/* --- VARIABLE-LENGTH ARGUMENT LISTS --- */
/* For convenience, FWEB attempts to use functions with variable numbers of \
arguments. We attempt to support two conventions: ANSI, and Sun's. If \
this feature is supported, define the flag |VARIABLE_ARGUMENTS|, say \
whether |va_start| has one or two arguments, and include the associated \
header file (<stdarg.h> for ANSI). */

(ANSI)? */

/* --- ADDITIONAL PROTOTYPES --- */
/* You may wish to collect any additional prototypes that are required and \
put them into your own header file that you include here. */
/* If the flag |HAVE_STD_PROTOTYPES| is false, it causes the file \
"stdlib0.h" to be loaded. This contains ANSI prototypes that for some \
reason aren't provided with the gcc environment on the Sun. */
/* (The flag |HAVE_STD_PROTOTYPES| is set automatically in config.h by ./configure.) */
/* Define the flag |OLD_PROTOTYPES| for compilers that don't support the \
new (ANSI) style of function declaration and prototyping. The new style is \
|fcn(int i,char *s){}|; the old style is |fcn(i,s) int i; char *s; {}|. */

/* ANSI also introduces the type |void|. If your compiler doesn't \
understand the constructions |void *| and |void fcn()|, define |NO_VOID|. */
/* (The flag |NO_VOID| is set automatically in config.h by ./configure.) */
/* --- SPECIAL TYPES --- */
/* |const| seems to be an annoyance; not all compilers treat it the same \
way. We really only want it for debugging, anyway, so we mostly just \
remove it. It's kept when compiling on the Sun with gcc, because it \
gives the developer more checks on the code. If you want to keep it, \
define |KEEP_CONST|. */

/* For personal computers, the kind of pointer is an issue. They must be \
|huge|. If your compiler understands |huge|, define |HUGE_POINTERS|. */

/* --- SPECIAL FUNCTIONS --- */
/* The ANSI |sprintf| function returns the number of characters written. \
If this is the case on your system, define |ANSI_SPRINTF|. (It's always \
safe to not define it.) */
/* (The flag |ANSI_SPRINTF| is set automatically in config.h by ./configure.) */
/* The ANSI |sscanf| does some cute things with scansets, but it doesn't \
always work. */
/* (The flag |ANSI_SSCANF| is set automatically in config.h by ./configure.) */
/* The ANSI |system| function is supposed to take |NULL| as an argument, \
which means check if a command processor exists. If this works properly, \
defined |ANSI_SYSTEM|. (It doesn't work on the Sun.) */
#define ANSI_SYSTEM 0
/* --- ANNOYING WARNINGS --- */
/* Sometimes the compiler can't understand that the \
control flow can never get to the bottom of a function. To avoid warning \
complaints, we have the following: */
#define DUMMY_RETURN(value) return value
/* --- UNUSUAL NAMES --- */
/* Put here any definitions that override standard names. For example, for \
some ancient on the MAC one had to say ``#define getc agetc''. */
/* Nothing to be done. */
/* --- DIRECTORY SPECIFICATIONS --- */
/* Directory specifications are delimited in different ways under the various \
operating systems. Unix: '/'; IBM-PC: '\\'; VAX/VMS: ']'. */
#define PREFIX_END_CHAR '/' /* The Unix convention. */
/* --- TIMING --- */
/* First of all, we have a flag to say whether timing information is \
printed at the end of the run. (If you can't figure out the timing \
routines for your machine or don't want a timing information line at the \
end of your terminal output, don't define this.) Beginning with fweb-1.53, \
timing is turned off by default. */
#define TIMING 0
/* --- Number of decimal places for timing information in seconds. (Use \
at least 2 for supercomputers.) --- */
#define TIMING_WIDTH 1
/* There's supposed to be a function |clock()| that returns the cpu time, \
in units of |CLOCKS_PER_SEC|. The type of |clock| is |clock_t|. If that \
is defined, define the flag |CLOCK_T_DEFINED|; otherwise, say |typedef ... \
clock_t| here. */
/* (The flag |CLOCK_T_DEFINED| is set automatically in config.h by ./configure.) */
/* Some systems don't define |CLOCKS_PER_SEC|. If not, we try |CLK_TCK|. \
If that's not defined, it defaults to 1000000. If that's not appropriate, \
define |CLOCKS_PER_SEC| here. */
/* \
#define CLOCKS_PER_SEC 1000000 \
*/
/* Are there system routines that return wall-clock time in sub-second units? \
First, look for |gettimeofday| ($\mu$sec timing). */
/* (The flag |HAVE_GETTIMEOFDAY| is set automatically in config.h by ./configure.) */
/* Otherwise, does the file sys/timeb.h exist that along with |ftime| gives \
millisecond timing for wall-clock time? We check for the header file, not \
|ftime| itself, since |ftime| may be in a Berkeley compatibility library, \
not in libc. */
/* (The flag |HAVE_SYS_TIMEB_H| is set automatically in config.h by ./configure.) */
/* Do we use our own version of |difftime()|, which computes the difference \
of two wall clock times? If so, define |NEW_DIFFTIME|. This flag should \
always be defined if |HAVE_SYS_TIMEB_H| is defined above. */
/* |NEW_DIFFTIME| is computed from flags set by ./configure. */
/* --- MAKING IT FIT --- */
/* Sometimes the compiler can't handle functions or switches that are too \
large. In that case, define |FCN_CALLS|. That converts certain in-line \
code (such as in the syntax production analyzer) into function calls (at \
the price of slowing things down a bit). */
#define FCN_CALLS 0
/* The personal computers are starved for memory. For those machines, we \
specify smaller default values for the lengths of dynamic arrays; define \
|SMALL_MEMORY|. (You can always use the `-y' option to override these \
defaults.) */

conventions unless you absolutely have to!!! Also, note that these \

*calloc(size_t,size_t)|. If the system doesn't have a standard |calloc| \
routine, or if the name isn't standard, you must define an UPPERCASE macro \

because one is dealing with |huge| allocations.) If you define \
|NON_ANSI_CALLOC|, you must define |CALLOC|, |REALLOC|, and |FREE|. E.g., the \
