title: Gcc default version crashes
body: <p>I working on open source GHDL project for my project purpose installed <code>ghdl-0.29-2.143svn.4.fc16.src.rpm</code> consisting of <em>ghdl 0.29</em> and <em>gcc 4.3.4</em> through <code>rpm -i</code> and <code>rpmbuild -ba</code> command successfully. </p>
  
  <p>In ghdl folder, I edited one ada program then I did <code>make</code> and <code>make install</code> : no errors but it creates problem changes in gcc version 4.6.3 (default) to 4.3.4 and no gcc program execution gave error:</p>
  
  <pre><code>error: C compiler cannot create executables
  See `config.log' for more details." 
  In config.log file /usr/bin/ld: cannot find crtbegin.o: No such file or directory
  /usr/bin/ld: cannot find -lgcc
  /usr/bin/ld: cannot find -lgcc_s
  collect2: ld returned 1 exit status
  </code></pre>
