/* On Unix-like systems config.in is converted by "configure" into config.h.
Some other environments also support the use of "configure". PCRE is written in
Standard C, but there are a few non-standard things it can cope with, allowing
it to run on SunOS4 and other "close to standard" systems.

On a non-Unix-like system you should just copy this file into config.h, and set
up the macros the way you need them. You should normally change the definitions
of HAVE_STRERROR and HAVE_MEMMOVE to 1. Unfortunately, because of the way
autoconf works, these cannot be made the defaults. If your system has bcopy()
and not memmove(), change the definition of HAVE_BCOPY instead of HAVE_MEMMOVE.
If your system has neither bcopy() nor memmove(), leave them both as 0; an
emulation function will be used. */

character codes, define this macro as 1. On systems that can use "configure",

is exported by the library, define this macro to contain the relevant magic. If
you do not define this macro, it defaults to "extern" for a C compiler and
"extern C" for a C++ compiler on non-Win32 systems. This macro apears at the
start of every exported function that is part of the external API. It does not
appear on functions that are "external" in the C sense, but which are internal
to the library. */
