This small test program may help you figure out what's going wrong:

	print "\.*", "\n";
	print '\.*', "\n";

Backslash works differently inside single and double quotes.
Try:

      <skip: "\\.*">

The reason the third variant:

      <skip: "[\.]*">

works is because it becomes the pattern:

	/[.]/

which is a literal dot.
