Re: Emacs 22 Carbon+AppKit port and Emacs 23 Mac port

[CHENG Gao]

Out of curiosity, I tried to build Mac port (1.92) with clang, and found
it works well, while building 32bit ns port fails.

I compared building with gcc (4.2) and clang (on Snow Leopard), the
result is below:

1. With gcc 4.2

$time ./configure --with-mac

real    0m38.490s
user    0m8.163s
sys     0m10.563s

$time make -j3

real    2m21.291s
user    2m26.661s
sys     0m17.704s

2. With clang

$time CC='clang' ./configure --with-mac
real    0m20.890s
user    0m5.425s
sys     0m10.277s

$time make -j3
real    1m9.632s
user    1m33.100s
sys     0m13.372s

Seems clang is much faster than gcc.
