Compiling stb_image, an incredibly useful image loader:<p><pre><code>  $ wc -l stb_image.h
      6433 stb_image.h

  $ more stb_image.c 
  #define STBI_ONLY_JPEG
  #define STBI_ONLY_PNG
  #define STBI_FAILURE_USERMSG
  #define STB_IMAGE_IMPLEMENTATION
  #include &quot;stb_image.h&quot;

  $ time clang -c stb_image.c -o stb_image.o

  real	0m0.091s
  user	0m0.075s
  sys	0m0.014s
</code></pre>
Seems pretty fast to me!
