(svn r3265) -Fix: partly reverted back r3263, because MSVC, who else, doesn't support variadic macros............

(svn r3264) -Codechange: [OSX] OSX targets will now always use the preprocessor to determine endianess
this means that ENDIAN_FORCE is obsolite since it's always overwritten with PREPROCESSOR
Since the preprocessor should never be able to pick wrong, it's easier this way
specially when compiling universal binaries as they got both endianess

(svn r3263) -Fix: use () around 'variables' in macros, gives less crashes ;)
-Fix: va-args in macros are supported via __VA_ARGS__ in C99, so changed
to that; now GCC 2.95 likes it too :)

(svn r3262) -Fix: [OSX] universal binaries can now include the dynamic SDL lib into the bundle

(svn r3261) - Autoreplace: If a replaced vehicle had a custom name, transfer it to the new vehicle. Fixes "[ 1370039 ] Autoreplaced vehicles lose their names"

(svn r3260) -Add: add events for AIs to check if a command execution failed or succeeded

(svn r3259) -Fix: [OSX] fixed that universal binaries did not make a bundle

(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 r3257) -Codechange: [OSX] removed the dynamic lib in bundle option (introduced in rev 3230)
it caused way more problems than it solved

(svn r3256) -Fix: [OSX] fixed issue where building the bundle could take place before linking if -j 2 was used
