Comment(by z@…):

 We haven't tried on PowerPC yet that is why we have chosen X86 only. We
 will manage to get a Power PC in a few weeks but this is not our priority.

 ''CXXFLAGS=-fno-strict-aliasing'' is useful on Lion only. With some
 variants of gcc 4.2 while compiling with '-O3', binaries produced are
 wrong and crash. Snow Leopard and Lion both use Apple's gcc 4.2 however
 this is not the same exact version.

 We have encountered issues on Lion with : i686-apple-darwin11-llvm-gcc-4.2
 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00). Using this
 flag, make it work. This is because we do some magic with pointers in some
 parts of our code and this particular version of gcc gets confused with
 it.

 With other standard gcc compilers provided through mac ports, no issue
 have been encountered.
 This project is tested under Debian Linux using gcc 4.1, 4.2, 4.4, 4.6 and
 on Mac OS Lion/Snow Leopard with llvm-gcc-4.2.
