OK, I think I've found something that will work for me (at least for now). The "Unexported Symbols File" setting in Xcode will do what I need it to do. However, there is a problem. It seems that the symbols that are exported by GCC 3.3 and GCC 4.0 are different and I cannot create an "Unexported Symbols File" that will work with both compilers. I need GCC 3.3 for PPC and obviously GCC 4.0 for Intel.

I had hoped that I'd be able to do something like this:

UNEXPORTED_SYMBOLS_FILE_ppc  = Excluded_Symbols_ppc.exp
UNEXPORTED_SYMBOLS_FILE_i386 = Excluded_Symbols_i386.exp

But this setting doesn't work with the _ppc & _i386 suffixes. So what can I do to use different Unexported Symbols Files?

I think you can add something like
UNEXPORTED_SYMBOLS_FILE = $(UNEXPORTED_SYMBOLS_$(CURRENT_ARCH))
to use either the _ppc or the _i386 version.

It occurs to me that you could just do
UNEXPORTED_SYMBOLS_FILE = Excluded_symbols_$(CURRENT_ARCH).exp
instead and not have the other two.
