Changes to the WRPRC configuration distribution for Release 1.04
16 Dec 1992

o	Added -I to imkmf so you can specify project-specific configuration
	directory other than default of ${TOP}/config.

o	-d is always the default for imkmf now.  Use -u to turn it off.
	This results in a slight incompatibility with xmkmf (see man page).

o	Some other stuff. :-)
