What you need to try is putting -arch ppc -arch i386 for both the
CXX_FLAGS and C_FLAGS using ccmake.
That works for me in 10.4.11 with gcc.
Actually, there is full support for universal binaries in CMake.
If you set this cmake cache variable:
CMAKE_OSX_ARCHITECTURES=ppc;i386
Or set the same name environment variable before running CMake, the
makefiles or Xcode will produce OSX universal binaries.

Funny.. last time I asked I was told to use "i386 ppc" which did not
work and so I started adding the flags myself. Using a ";" instead of
a space does allow universal binaries to be produced.
Of course one has to be careful when doing this with endian specific
code. Have both PPC and i386 is basically cross compiling and trying
to determine the proper byte ordering of the target machine is prone
to errors. Just FYI for those with this type of code.
Thanks for the correction Bill.
