title: gcc not working on mac
body: <p>I have <strong>updated to Xcode to v4.2.1 from v3</strong> and it works fine but as a C newbie I want to code in Text Wrangler and compile with gcc in the CLI.</p>
  
  <p>gcc returns 'command not found' for some reason now (it worked fine earlier)</p>
  
  <p>After some googling I figured out <strong>gcc was moved to /Developer/usr/bin from /usr/bin</strong> (I can see it there).
  Now gcc runs when I use the exact path but it <strong>can't find any of the header files.</strong></p>
  
  <pre><code>my-MacBook-Pro:Desktop user$ /Developer/usr/bin/gcc -o program  program.c 
  program.c:15:19: error: stdio.h: No such file or directory
  program.c:16:18: error: math.h: No such file or directory
  program.c:17:20: error: stdlib.h: No such file or directory
  program.c: In function ‘main’:
  program.c:33: warning: incompatible implicit declaration of built-in function ‘malloc’

  program.c:44: warning: incompatible implicit declaration of built-in function ‘printf’
  program.c:65: warning: incompatible implicit declaration of built-in function ‘printf’
  </code></pre>
  
  <p>Any help is greatly appreciated.</p>
