/*************************************************
* PCRE testing program *
*************************************************/
/* This program was hacked up as a tester for PCRE. I really should have
written it more tidily in the first place. Will I ever learn? It has grown and
been extended and consequently is now rather, er, *very* untidy in places. The
addition of 16-bit support has made it even worse. :-(

/* This program now supports the testing of all of the 8-bit, 16-bit, and
32-bit PCRE libraries in a single program. This is different from the modules
such as pcre_compile.c in the library itself, which are compiled separately for
each mode. If two modes are enabled, for example, pcre_compile.c is compiled
twice. By contrast, pcretest.c is compiled only once. Therefore, it must not
make use of any of the macros from pcre_internal.h that depend on
COMPILE_PCRE8, COMPILE_PCRE16, or COMPILE_PCRE32. It does, however, make use of
SUPPORT_PCRE8, SUPPORT_PCRE16, and SUPPORT_PCRE32 to ensure that it calls only
supported library functions. */

using a single macro to do this in a generic way, because of the many different
argument requirements. We know that at least one of SUPPORT_PCRE8 and
SUPPORT_PCRE16 must be set. First define macros for each individual mode; then
use these in the definitions of generic macros.
**** Special note about the PCHARSxxx macros: the address of the string to be
printed is always given as two arguments: a base address followed by an offset.
The base address is cast to the correct data size for 8 or 16 bit data; the
offset is in units of this size. If the string were given as base+offset in one
argument, the casting might be incorrectly applied. */

same match if the original start offset was bumped along during the
match, but eventually the new start offset will hit the actual start
offset. (In PCRE2 the true start offset is available, and this can be
done better. It is not worth doing more than making sure we do not loop
at this stage in the life of PCRE1.) */
