title: Syntax Coloring Not Working as Expected in VIM Editor 6.3 on AIX 5.3
body: <p>I enabled syntax highlighting for my C files by issuing the command <code>:syntax on</code>. I expected it to change the colors of keywords etc. But to my surprise, syntax highlighting is happening, but all keywords are being underlined instead of being colored!</p>
  
  <p>Am I missing out something?</p>
