Jan 30 (Reuters) - Most Southeast Asian stock markets gained on Wednesday, with the Philippines hitting a record high for the third day running and Thailand at a more than 18-year high ahead of the U.S. Federal Reserve's monetary policy decision. The Philippine Composite Index ended 0.6 percent firmer at a record closing high of 6,271.23, after hitting a fresh intraday peak of 6,320.60.
