<p>The <samp>gcc</samp> directory is configured with an Autoconf-generated
script <samp>configure</samp>. The <samp>configure</samp> script is generated
from <samp>configure.ac</samp> and <samp>aclocal.m4</samp>. From the files
<samp>configure.ac</samp> and <samp>acconfig.h</samp>, Autoheader generates the
file <samp>config.in</samp>. The file <samp>cstamp-h.in</samp> is used as a
timestamp.
