(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 r3280) Merge the seperate (C|CXX|OBJC)_SOURCES variables into a single variable SRCS
Now adding a new file to compile is just adding a line like SRCS += $(FIILE), regardless of type

(svn r3279) -Fix: do not try to execute something that is not set to execute
-Fix: do not increase an uid number if it isn't returned

(svn r3278) -Fix: lets update the tail-pointer if we add a new item, else the linkedlist never grows ;)

(svn r3277) -Fix: lets use the right DoCommand for testing a build (tnx to Igor2Code)

(svn r3276) reverted the last two commits. OSX 10.2 kept finding new stuff to prevent it from running OpenTTD, so now it's not supported anymore

(svn r3275) -Fix: [OSX] removed libpng support and error dialogs from jaguar crosscompiles to fix crash

(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 r3272) -Fix: [AI] fixed issue in AI that prevented compilation without network support
