	I am having a problem linking with MPW.  When my programs use the
"is" (e.g. isalpha, iscntrl, isdigit, isupper, etc) functions from the file
<CType.h> the linker complains:
	### Link: Error: Undefined entry, name: (Error 28) "_CType"

I have linked the particular program with every C library I could find, but to
no avail.

	I think this has something to do with the 3.1 (3.0?) C libraries, or
with the new C++ libraries.  I was not having these problems before I installed
one of these packages (I can't remember which).

Environment:
	MPW Shell 3.1
	C 3.1
	Libraries 3.0
	CLibraries 3.0
	CPlusLibraries 3.1B1

_CType as defined in <CType.h>:
	extern char 	 _CType[];

Does any one have a clue as to what is going on?  Is there a fix for this
problem?  Is there a problem?
