	So, your saying after I change the dll I should recompile the
	software I'm trying to port?

	Well, I created a /etc/passwd and /etc/group.  I guess my
	confuse lies in that all I did was change the DLL, I didn't mess
	with the CYGWIN variable or any of the other cygwin settings/config
	files.  Does the CD cygwin1.dll have different defaults than

	the creation of the passwd and group, the CD version of the DLL
	didn't really care either way.

	I know, I just wanted to make sure it is compatible with
	the 2.95 compiler.
