After seeing Dan's comment, I realize that even http://... stuff would
be changed, so the previous regexp is no good. 

This is the new regexp, which relies on the fact that stuff in
comments should not be matched.

#!/usr/bin/perl
while (<>) {
      s/^(.+?)\/\/(.*)$/\1\/\*\2\*\//;
      print;      
}

It still does not fix anything inside existing /* */'s, but should be
fine for fixing code with only // as comments.
