(svn r3596) -Codechange: [OSX] changed to use Apple's macros instead of OTTD macros for endian conversion
This increases the execution speed a lot since GCC can't detect the OTTD macro as an endian conversion
while Apple's code uses the instruction to convert endian instead of a series of instructions to produce the same result

Since we don't have that many endian conversions in the game, overall performance should not increase noteworthy
