2 * PCRE testing program *

5 /* This program was hacked up as a tester for PCRE. I really should have
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.

63 makes no difference on Unix-like systems.) Later I was told that it is wrong

65 are set here, to make it easier to fiddle with them, and removed "b" from the
