[PATCH] cygcheck: follow symbolic links

[Igor Peshansky <pechtcha at cs dot nyu dot edu>]

As promised in <http://cygwin.com/ml/cygwin/2006-02/msg00071.html>, the
attached patch teaches cygcheck to follow symlinks when looking for
executables, and also flags scripts.  Sorry, had legal delays in sending
this (as you can see, I had this working since 02/03).  Comments welcome.

	* cygcheck.cc (LINK_EXTENSION): New macro.
	(check_existence): New static function.
	(find_on_path): Check for symbolic links if asked.
	(EXE_MAGIC,SHORTCUT_MAGIC,SYMLINK_COOKIE,SYMLINK_MAGIC): New
	macros.
	(is_exe,is_symlink,readlink): New static functions.
	(track_down): Only call dll_info() for executables, display
	an error for symlinks, and print magic number for others.
	(find_app_on_path): New static function.
	(cygcheck, dump_sysinfo): Call find_app_on_path() instead of
	find_on_path().
