/*************************************************
* PCRE2 testing program *
*************************************************/
/* PCRE2 is a library of functions to support regular expressions whose syntax
and semantics are as close as possible to those of the Perl 5 language. In 2014
the API was completely revised and '2' was added to the name, because the old
API, which had lasted for 16 years, could not accommodate new requirements. At
the same time, this testing program was re-designed because its original
hacked-up (non-) design had also run out of steam.

/* This program supports testing of the 8-bit, 16-bit, and 32-bit PCRE2
libraries in a single program, though its input and output are always 8-bit.
It is different from modules such as pcre2_compile.c in the library itself,
which are compiled separately for each code unit width. If two widths are
enabled, for example, pcre2_compile.c is compiled twice. In contrast,
pcre2test.c is compiled only once, and linked with all the enabled libraries.
Therefore, it must not make use of any of the macros from pcre2.h or
pcre2_internal.h that depend on PCRE2_CODE_UNIT_WIDTH. It does, however, make
use of SUPPORT_PCRE2_8, SUPPORT_PCRE2_16, and SUPPORT_PCRE2_32, to ensure that
it references only the enabled library functions. */

Before including pcre2_internal.h we define PRIV so that it does not get
defined therein. This ensures that PRIV names in the included files do not
clash with those in the libraries. Also, although pcre2_internal.h does itself
include pcre2.h, we explicitly include it beforehand, along with pcre2posix.h,
so that the PCRE2_EXP_xxx macros get set appropriately for an application, not
for building the library.
Setting PCRE2_CODE_UNIT_WIDTH to zero cuts out all the width-specific settings
in pcre2.h and pcre2_internal.h. Defining PCRE2_PCRE2TEST cuts out the check in
pcre2_internal.h that ensures PCRE2_CODE_UNIT_WIDTH is 8, 16, or 32 (which it
