New multiple symbols warnings under Tiger

We have a Cocoa app that has been building with no warnings under
Xcode 1.5/Panther. When building this application using Xcode 2.0/
Tiger, linking against the Accelerate framework leads to numerous
warnings about multiple definitions of symbols in the math library:
(see below).
Anyone else getting this kind of thing? Any ideas on the cause or a
fix? I have tried a number of reorganizations but nothing seems to
get rid of these without removing needed symbols.
I am building frameworks that are linked into a main app as well as
plugins.
Thanks for any suggestions,
Rick
