The Build utility puts a file in the obj subdirectory called _objects.mac that contains the object dependencies for each platform.
A typical _objects.mac file looks similar to the following code example:
386_OBJECTS= \ $(_OBJ_DIR)\i386\x.obj \ $(_OBJ_DIR)\i386\y.obj PASS0_386_OBJECTS= IA64_OBJECTS= \ $(_OBJ_DIR)\ia64\x.obj \ $(_OBJ_DIR)\ia64\y.obj PASS0_IA64_OBJECTS=
This file is created by the Build utility. You do not have to edit it. Every time that the Sources file is updated, this file is regenerated.
