Although not a compiler efficiency problem, I have noticed that when LSC links together a file which uses a certain library, it includes the entire libary even if only one procedure/func in the lib is actually called.  When it links in a project, each object in the project (or whatever you wish to term it) is linked in in its entirety even if only one proc/func w/in it is actually called.

I know that this id documented...  I'd guess that it's probably done bec. it's faster....  and I can understand that.  But when the Build Application (or code/da) is invoked, I feel that we should have the option of having the final form of the prgm optimized.

Before, using the MacTraps w/2.01, I've had relatively small prgms (20-35k) come out 3-8k smaller than they do now under the 2.11 MacTraps.  Those numbers add up
