note that you probably don't want to add your source files to the 
"merge" target, i.e. the target w/o  PPC or C68k in the name

watch out to add these only to the appropriate targets i.e. 
TkStub.lib to PPC, TkStubCFM68K.lib to C68k

no, these entries are generated automatically to match the object 
files produced by the PPC and C68k targets, to change their names, 
change names in options "PPC Target" resp "68k Target"

yep, see above

normal, harmless, due to bad library design on MW's part

strange, shouldn't happen if you CW is setup properly

are you sure you have:

* system access paths include {Compiler}:MacOS Support
* your MacOS Support folder setup as follows: (the .r files are in RIncludes)
MacOS Support:
	Universal:
		Interfaces:
			AIncludes:
			CIncludes:
			ComponentIncludes:
			PInterfaces:
			RIncludes:
		Libraries:
			Classic68kLibraries:
			PPCLibraries:
			StubLibraries:

yep, see above

but given that you removed the object entries in the project, it 
probably doesn't anymore... to fix this, go into the targets panel, 
click on the disclosure triangle for your merge target and click in 
the column below the chain-link icon for both of the italicized lines 
for the PPC and 68k targets

see above, shouldn't need to do that, but it will do the trick

no, this is due to another screwup on MW's part, I've explained the 
fix in my Tcl/Tk 8.3.2p1 distro, in the file (Pro6 Build Support):CW 
Pro6 changes, I've reproduced the relevant instructions for your 
problem below...

- in
	MacOS Support:Libraries:MacOS 
68K:MathLib68K:(Projects):MathLibCFM68K.MTarg.mcp
enable
	CFM68k->ForceIndirectAccess
for both targets and rebuild



That should do it, hope everything works now

Cheers,

Daniel
