Now OSX stores object files in .OSX and instead of making FAT object files, there are one for each architecture
Each architecture got their own targets to make a non-FAT binary and in the end, lipo will merge them into one binary
It's now possible to select which architectures you want to support by defining OTTD_PPC, OTTD_PPC970 (G5) and/or OTTD_i386
All combos are supported. UNIVERSAL_BINARY and TRIPLE_BINARY can still be used even though it's possible to gain the same result by using the new flags
Making a universal build when you already got part of it compiled (say the PPC part), it will reuse it and only compile the i386 part to save time
Note: in some cases when you switch flags, you risk that openttd is not updated. Delete it and try again. The Makefile can't solve this except if it forces linking each time
This fixes: FS#87 universal binary building borked in 0.4.7
Now universal binaries work on OSX 10.3.9 again
Building universal binaries no longer needs to store flags in Makefile.config as the new design makes it possible to figure everything out automatically

calling itself. NOTE: Delete Makefile.config to recover.

present in the system
if detected, WITH_ICONV will be defined in the C code
WITH_ICONV is also added to Makefile.config
OSX do not use this flag setting in Makefile.config, as it is set at compile time based on target OS version
the actual C code is not changed as the current iconv code is hardcoded for OSX and would break if any other OS got iconv
This detection system is by request of Darkvater

in 10.3
this have the sideeffect that 10.2.8 will still have the "failure to save with certain chars in the filename bug", but at least it can compile again

binaries are build
Instead of compiling a binary for each arch and then join them in the end, each .o file is now compiled as a fat file
This means that the makefile will not call itself to make a binary for each target and we don't have to make clean between each build
it also means that if one file changed, we don't have to recompile all files
Another benefit is since it's handled at .o level and though LDFLAGS, no special code is needed if we decide to compile more binaries (like a lot of stuff used to happen at post linking)
We also needs much less flags to set up, so it should be even easier to get to work out of the box now
The tradeoff in doing so is that now the binary needs at least OSX 10.3.9 to execute
To deal with this issue, the JAGUAR flag can be used to compile for older OSes. We will release a binary for old OSes at next release to see if anybody even downloads it (not that many people use OSX 10.2 anymore)
GPMI will not work on 10.2 anyway so we will cut support for it some day anyway

denied in G5_detector.c when compiling without having Makefile.config

binaries into the newest gcc for each target instead of hardcoding it for 4.0.0

optimised for G3, G5 and i686)
G4 have no problems using G3 code while G5 can, but really benefit from getting their own optimised code (Apple: G5 is not just a fast G4)
Also changed FAT_BINARY to UNIVERSAL_BINARY since Apple removed most (all?) references to fat binaries on their homepage two days after I added FAT_BINARY

compiles on G5 and then adds flags to optimise for G5
This will not interfere with crosscompiling or universal binaries
|
|
caused problems for non-SDL builds
FAT binaries now need to rely on COCOA drivers. SDL didn't work properly anyway

10.2.8 on 10.4

to prevent it from running OpenTTD, so now it's not supported anymore

crosscompiles to fix crash

(codenamed jaguar)
JAGUAR and FAT_BINARY can't be used at the same time
JAGUAR will disable network support due to missing libs in 10.2
|
|
instead of 10.4
10.2 support appears to be broken right now
Changed BUILD_UNIVERSAL_BINARY into FAT_BINARY (I got tired of typing)

now PPC code is always compiled before x86 code
strgen and lng files are only compiled once, which results in shorter building time
the makefile now assigns default values to undefined values so much less needs to be set up
the code is now easier to maintain
