title: Why cscope don't search definitions in header files?
body: <p>I use the following command to generate my cscope database:</p>
  
  <pre><code>tmpfile=$(mktemp)
  find dir1/ dir2/ dir3/ -type f -regex ".*\.\([chlysS]\(xx\|pp\)*\|cc\|hh\|inl\|inc\|ld\)$" -print &gt; $tmpfile
  cscope -q -b -U -i $tmpfile -f cscope.out
  </code></pre>
  
  <p>Into vim, a <code>:cs f g myfunction</code> only leads me to the definition in C file, and nether in header file.</p>
