[MACTCL] message from ld after building tcl-8.4.3 on MacOS X 10.2.6

[<gbj...@at...>]

Platform: Ti PowerBook running MacOS X 10.2.6 with Dec Developer Tools

I just build tcl-8.4.3 with the usual:

$ cd tcl-8.4.3/unix
$ ./configure
$ make

The linker emitted this message in the last step of the build:

ld: warning dynamic shared library: /System/Library/Frameworks/CoreFoundation.framework/
CoreFoundation not made a weak library in output with MACOSX_DEPLOYMENT_TARGET 
environment variable set to: 10.1

Does anyone know it's meaning? Is anything wrong?  Answers or pointers welcome.
TIA.
