2 /* On Unix systems config.in is converted by configure into config.h. PCRE is
3 written in Standard C, but there are a few non-standard things it can cope
4 with, allowing it to run on SunOS4 and other "close to standard" systems.
5
6 On a non-Unix system you should just copy this file into config.h, and set up
7 the macros the way you need them. You should normally change the definitions of
8 HAVE_STRERROR and HAVE_MEMMOVE to 1. Unfortunately, because of the way autoconf
9 works, these cannot be made the defaults. If your system has bcopy() and not
10 memmove(), change the definition of HAVE_BCOPY instead of HAVE_MEMMOVE. If your
11 system has neither bcopy() nor memmove(), leave them both as 0; an emulation
12 function will be used. */

22 /* The following two definitions are mainly for the benefit of SunOS4, which
23 doesn't have the strerror() or memmove() functions that should be present in
24 all Standard C libraries. The macros HAVE_STRERROR and HAVE_MEMMOVE should
25 normally be defined with the value 1 for other systems, but unfortunately we
26 can't make this the default because "configure" files generated by autoconf
27 will only change 0 to 1; they won't change 1 to 0 if the functions are not
28 found. */

33 /* There are some non-Unix systems that don't even have bcopy(). If this macro
34 is false, an emulation is used. If HAVE_MEMMOVE is set to 1, the value of
35 HAVE_BCOPY is not relevant. */

39 /* The value of NEWLINE determines the newline character. The default is to
40 leave it up to the compiler, but some sites want to force a particular value.
41 On Unix systems, "configure" can be used to override this default. */
