title: How to set gcc 4.3 default specs file?
body: <p>When using gcc version 4.3.2, I see how to generate specs using:</p>
  
  <pre><code>$ /usr/local/gcc-4.3.2/bin/gcc -v
  Using built-in specs
  </code></pre>
  
  <p>Now changing to the same directory as libgcc:</p>
  
  <pre><code>cd /usr/local/gcc-4.3.2/lib/gcc/x86_64-unknown-linux-gnu/4.3.2
  /usr/local/gcc-4.3.2/bin/gcc -dumpspecs &gt; specs
  </code></pre>
  
  <p>I have a populated specs file that I can modify.  However, once that is done I still see that:</p>
  
  <pre><code>$ /usr/local/gcc-4.3.2/bin/gcc -v
  Using built-in specs
  </code></pre>
  
  <p>How do I tell gcc to use that specs file by default rather than forcing me to pass a <code>-specs</code> parameter every compile?  I would like it to match another system I have where I get the following:</p>
  
  <pre><code>$ /usr/local/gcc-4.3.2/bin/gcc -v
  Reading specs from /usr/local/gcc-4.3.2/lib/gcc/i686-pc-linux-gnu/4.3.2/specs&lt;/code&gt;
  </code></pre>
  
  <p>As you can see, the major difference between the two systems is that the existing setup is 32-bit and I am now trying to match that on a 64-bit system.  The version of Linux is otherwise the same and I am compiling the same version of gcc.  (With both systems gcc 4.3.2 is the second gcc installation, with 4.1.2 being used to compile 4.3.2)</p>
