Reply-To:	djgpp-workers AT delorie DOT com

Currently fixproto script does not understand DOS style absolute
paths with drive letters. This leads to paths like d:/gcc/obj/c:/djgpp/include
which are incorrect and cause infinite recursion while fixproto'ing
limits.h.

This patch rewrites absolute path checks to make them like in another
script, ylwrap.

(Andris, is it useful in anyway for your 2.95.2 port?)

	* fixproto: Recognize DOS paths with drive letters as absolute paths.
