Hmm. All those "IPA object files foo and bar have been compiled with
different settings..." warnings are pretty dubious. I have no clue what
would cause those-- can you send the output of "make clean all"? I'd like
to see the options that were used to compile those .o files.
First guess, however, is that this is somehow the compiler's fault --
LAM's build process will not put in all those different flags during the
build.
Another possibility is that you did not run "make clean" in the build tree
between compiling for 32 and 64 bits. Could that have happened?
