I have two different Macintosh computers  each running OSX.

Machine A: A Power-PC-based G5 running Panther 10.4.11, with xcode 
version 2.4.1 which uses gcc-3.3

Machine B: An Intel CoreDuo-based iMac running Leopard 5.3, with 
xcode version 3.0 which uses gcc-4.0

On Machine A I compile my application and it builds with no errors, 
and then runs correctly.

On Machine B, during the build, xcode returns a "Duplicate Symbol" 
error (i.e. the same symbol in two different .o files) during the 
link stage

The duplicate symbol name identified by xcode on Machine B differs 
depending on whether I build for "Release" (symbol name claimed is 
"_flag") or for "Debug" (the duplicate symbol name claimed is 
"_verbose").

I do not use either of these symbol names in my code so they must 
have been generated during the build.  I do not understand what is 
going on here and would value some suggestions as to how to find and/
or eliminate the error.
