6    written it more tidily in the first place. Will I ever learn? It has grown and
7    been extended and consequently is now rather, er, *very* untidy in places. The
8    addition of 16-bit support has made it even worse. :-(

39    /* This program now supports the testing of all of the 8-bit, 16-bit, and
40    32-bit PCRE libraries in a single program. This is different from the modules
41    such as pcre_compile.c in the library itself, which are compiled separately for
42    each mode. If two modes are enabled, for example, pcre_compile.c is compiled
43    twice. By contrast, pcretest.c is compiled only once. Therefore, it must not
44    make use of any of the macros from pcre_internal.h that depend on
45    COMPILE_PCRE8, COMPILE_PCRE16, or COMPILE_PCRE32. It does, however, make use of
46    SUPPORT_PCRE8, SUPPORT_PCRE16, and SUPPORT_PCRE32 to ensure that it calls only
47    supported library functions. */
