Our current Mac OS X builds use GCC-4.2.
On Python2.7, I ran a comparison of gcc-4.2.1 builds
versus gcc-4.8.1 and found that the latter makes a much
faster Python. PyBench2.0 shows the total running time
dropping from 5653ms to 4571ms. The code is uniformly
better in just about every category.
I know that newer Microsoft compilers tend to drop support for older
operating systems, and often that means the binaries simply won't work
on those operating systems. (Yes, technically it's the libraries that
break the older code.)
Are Apple's compilers the same? Or do they tend to support all the old
versions of OS X?
