(svn r4183) -Codechange: [Makefile]: removed MANUAL_CONFIG as it's not used anymore
This should hopefully fix the issue where WITH_SDL can be defined while SDL-CONFIG is not
Added an error if WITH_SDL is defined but SDL-CONFIG is not. The same goes for WITH_PNG even though nobody reported this as a problem
removed STATIC_ZLIB_PATH as it turns out that nobody used it

(svn r4149) -Codechange: [OSX] rewrite of how universal binaries are compiled
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

(svn r4074) -Feature: [Makefile] the makefile can now detect if iconv is 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

(svn r3882) -Codechange: [OSX] changed the way universal and tripple 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

(svn r3383) -Code cleanup: [OSX] removed SDL support from FAT binaries as it caused problems for non-SDL builds
FAT binaries now need to rely on COCOA drivers. SDL didn't work properly anyway

(svn r3313) Remove GPMI related changes from trunk
Revisions in detail: 2542, 3226 (partial), 3229, 3231, 3232, 3238, 3242-3245, 3251, 3253, 3260, 3263, 3265, 3266, 3269, 3277, 3278, 3279, 3283 (partial), 3304, 3305, 3306

(svn r3281) -Feature: [OSX] added native cocoa sound and video drivers (egladil)
you can still use SDL drivers if you like and you have to run "make upgradeconf" to start using the cocoa drivers (or manually write WITH_COCOA:=1)
since SDL breaks the cocoa drivers, you can't compile with both SDL and cocoa support
Using cocoa drivers makes it easier to make universal binaries and it solves:
-FS#18 [OSX] SDL is weird in universal binaries
-FS#2 [OSX] lazy pointer crash on exit
-FS#10 [OSX] linking error when linking statically to SDL 1.2.8 (needless to explain this, but it means it should be able to compile statically with the default settings now)
-[ 1215073 ] Switching to large size out of fullscreen crashes
Using SDL drivers will still have those issues though

(svn r3274) -Fix: [OSX] added JAGUAR flag to crosscompile for OSX 10.2 (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

(svn r3273) -Fix: [OSX] PPC part of universal binaries now target 10.3 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)

(svn r3267) -Codechange: [OSX] universal binary makefile code cleanup
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

(svn r3258) -Feature: [OSX] added support for universal binaries
it needs both PPC and x86 libs to compile
due to this fact, compilation with libPNG or SDL is not tested (dedicated servers only)
only PPC part is tested as I don't have x86 OSX

(svn r3230) -Feature: [OSX] OSX builds can now change where it searches for dynamic libs and can move libs into the bundle
This is not a fix for the issues with static linking, more like a workaround. Static linking still got issues
Apple recommends to use dynamic linking anyway, so I guess this doesn't matter much

(svn r3214) -Feature: openttd.cfg can now set how many autosaves to keep before starting to overwrite old ones
max_autosave_num in the config files sets the number of autosaves to keep (default 16)
MAX_NUM_AUTOSAVES in Makefile.config sets the default value. 16 is used if no value is given
this behaviour can still be overwritten by keep_all_autosave (openttd.config setting)
Note: this is a requested behaviour for PDA ports, since they got limited storage space

(svn r2712) Overhaul DirectMusic MIDI backend:
- Merge the .c and .cpp part into one file
- Properly deinitialize at the end
- Remove "experimental" status
- Miscellaneous smaller changes
-Fix: Volume control works now

(svn r2542) -Add: [GPMI] Added GPMI (http://sourceforge.net/projects/libgpmi/)
support to OpenTTD in preperation of AIScripts (long term). It is OFF
by default. Add GPMI:=1 to Makefile.config to enable.

(svn r2461) -Feature [Makefile] libpng-config can now be called something else in Makefile.config
useful if you for some reason got a libpng-config, which is called something else

(svn r2196) -Change: updated the Makefile, now it works for crossplatform compiling
(and distcc compiling via Makefile.config). Wiki is coming up soon! Big
tnx to Bjarni and Lucaspiller.

added completely customizable lang path (all non-Windows OSes)
