	Yes - I've done this quite successfully for large bits of Xlib with
	the standard release Self compiler.

	The trick is to _statically_ link the library into the .o file while
	making the .so file. Given your SmallFile.o 

		ld -o SmallFile.so SmallFile.o -Bstatic -lcps

Yes, this should be the safest bet. However, under SunOs 4.1.2 the Bstatic
should not be needed since the 4.1.2 version of ld.so has been extended
to do "transitive closure" of dynamic libraries. You'll still need the -lcps,
just not the -Bstatic. 

No guarantees, though....

	This worked for me under SunOS and gcc - of course, your mileage may
	vary. (At least we don't need sed on the assembler any more :-)
