title: No acceptable C compiler found in $PATH after installing Cygwin
body: <p>I want to install Kannel gateway on windowsXP. For that I downloaded and installed Cygwin. But when I went to configure the Kannel I got the following errors. (I set the PATH as C:\cygwin\bin;C:\libxml2-2.6.30+.win32\bin;)</p>
  
  <pre><code>Running system checks ...

  checking for gcc... no
  checking for cc... no

  configure: error: no acceptable C compiler found in $PATH
  See `config.log' for more details.
