+/*************************************************
+*              Do a JIT pattern match            *
+*************************************************/
+
+/* This function runs a JIT pattern match.
+
+Arguments:
+  code            points to the compiled expression
+  subject         points to the subject string
+  length          length of subject string (may contain binary zeros)
+  start_offset    where to start in the subject string
+  options         option bits
+  match_data      points to a match_data block 
+  jit_stack       points to a JIT stack 
+
+Returns:          > 0 => success; value is the number of ovector pairs filled
+                  = 0 => success, but ovector is not big enough
+                   -1 => failed to match (PCRE_ERROR_NOMATCH)
+                 < -1 => some kind of unexpected problem
