-lcc version 3.x is described in the book "A Retargetable C Compiler:
-Design and Implementation" (Addison-Wesley, 1995, ISBN 0-8053-1670-1).
-There are significant differences between 3.x and 4.x, most notably in

-UNLOAD THIS DISTRIBUTION ON TOP OF A 3.X DISTRIBUTION.
-
-LCC is a C89 ("ANSI C") compiler designed to be highly retargetable.
-
-LOG describes the changes since the last release.
