Subject: [PATCH] Fix warnings: syntax.c: syn_regexec(): Uninitialized arg: MI.

Problem    : Uninitialized argument value @ 2863.
Diagnostic : Multithreading issue.
Rationale  : Error can only occur if global `syn_time_on` is changed
             while the function is executing.
Resolution : Use local copy of gloval var.
