(But 4.0 is required for i386.)\n\nSetting the deployment target to 10.4 will disable prebinding, so for PPC, we set it less than 10.4 to preserve prebinding for legacy support.\n\nSetting the PPC SDKROOT to /Developers/SDKs/MacOSX10.2.8.sdk will link to 63.0.0 libSystem.B.dylib. Leaving it at current or 10.4u links to 88.1.2. However, as long as we are using gcc 3.3, it doesn't seem to matter as testing has demonstrated both will run. We have decided not to invoke the 10.2.8 SDK because it is not a default installed component with Xcode which will probably cause most people problems. However, rather than deleting the SDKROOT_ppc entry entirely, we have mapped it to 10.4u in case we decide we need to change this setting.\n\nTo use Altivec or SSE, we needed architecture specific flags:\nOTHER_CFLAGS_ppc\nOTHER_CFLAGS_i386\nOTHER_CFLAGS=$(OTHER_CFLAGS_($CURRENT_ARCH))\n\nThe general OTHER_CFLAGS needed to be manually mapped to architecture specific options because Xcode didn't do this automatically for us.\n\n\n";
