Fixed a few issues compiling with Mac OS X 10.6
Unfortunately the audio and cdrom systems do not build at all, and if you
disable those, SDL still fails to link with these errors:

12 Below is an overview of what we had to do to build Universal Binaries for SDL (and satellites). The document is provided to help others understand what the heck we had to do to get this to work so they know (and don't break) any settings we have set to accomplish this. It also describes areas of problems for those who might attempt to fix them after us.\ |

15 It turns out that developing a Universal Binary for SDL was a painful process, but not for the typical reasons affecting most other developers. SDL is already platform clean and has an Xcode project which are usually the two biggest obstacles. (The only real code bug we had to fix was in SDL_mixer, but that was due to a Quicktime issue so we can blame the Quicktime authors.)\ |

27 For retaining compatibility with 10.2, we have experimentally determined that there is no reliable way to use gcc 4.0.x to compile a binary that works under Jaguar. With the gcc 4.0 that shipped in Xcode 2.1, libgcc_s was automatically linked against. This library does not exist on systems prior to 10.3.9. After filing a bug report, Apple removed this automatic linking in gcc 4.0.1 which shipped with Xcode 2.2, but we discovered that we suffered from undefined symbols to things in the printf family library. (They seem to be new symbols related to printing long doubles, etc.)\ |

36 But we also needed to verify other options such as the deployment target and SDK. Experimentally, we found that the Deployment target did very little for us except retain prebinding. Setting it to anything less than 10.4 allows for prebinding to remain active.\ |

38 For the SDK's, we found that Apple does link against different versions of system components. But experimentally, we discovered we could still link to the 10.4u SDK and things would still work on Jaguar. Ideally we should probably link to the 10.2.8 SDK for PowerPC. But in reality, most people don't install the 10.2.8 SDK on their system (it is not a default component) so we didn't want to confuse people as setting this would likely cause people's compile to fail the first time they try and they would have to understand the reason for this. We did leave the architecture specific SDKROOT option set explicitly to make it easy to change in case we need to.\ |

40 For the Altivec and MMX/SSE options, we had to use architecture specific build flags. Furthermore, to use SSE, we also had to include the assembly code. This caused us problems because there is no easy way to tell Xcode to use files only for a specific architecture. So the PowerPC side got confused on the .asm files and would fail to compile. \ |

42 Pushing forward, we ignored PPC for the moment to see if we could at least build an optimized x86 build and then use lipo manually to merge the results. We encountered additional problems. First the alignment needed to be changed for reasons outside my knowledge base. We changed all instances of .align 16 to .align 8. This seemed to fix the compile problems. But at the linking stage, we got errors such as:\ |

50 Our belief is that the assembly code is not position independent and thus will not work for us. We double checked for any OS X gcc flags that control position independence, but everything seemed to be in order. As such, we cannot compile MMX/SSE optimizations until they are rewritten, preferably without the nasm requirement to accommodate the dual PPC/x86 Xcode limitations.\ |

71 We found that Apple already had a libfreetype in the 10.4u SDK so we just used that one which seemed to work.

So that's why.)\ |

75 libpng and libjpeg lack an Xcode project so we mucked with their build system to produce Universal Binaries. But since we needed PPC to be compiled with 3.3 and Intel to be compiled with 4.0, it ended up that we built multiple times changing the compiler, and then using lipo to strip and combine the binaries.\ |

79 It seems that once upon a time, the SDL_mixer framework supported MP3's via SMPEG, but this disappeared at some point. I don't know why or how this happened. But I also don't know how SMPEG was ever used with the framework as there was no preexisting infrastructure as with the other libraries. So I have attempted to correct this oversight, however, the SMPEG framework itself has MMX code which has also turned out to be problematic. I am getting compiler errors of " |

86 So SMPEG is currently compiled without MMX optimizations.\ |

93 The main SDL code base (not the satellites) have undergone an overhaul. The required platform specific defines have been moved out of the build system into platform specific header files (SDL_config_*.h). This allows us to simplify the Xcode projects somewhat, but we still must maintain the architecture specific build options to invoke gcc 3.3 to maintain our mandated 10.2 compatibilty requirement.\ |

95 Also it appears that the MMX/SSE code has been rewritten as well so that the obstacles we faced in compiling in these optimizations are no longer problems. The binaries we produce should now contain the processor specific optimizations. (Remember this note only applies to SDL and not the satellites, such as SMPEG.)\ |
