Is the following still true or has this been fixed meanwhile?

  <P>
    On some systems, it <EM>can</EM> be important that
    <TT>configure</TT> is run with the same optimization settings as
    used in the <TT>make</TT> step.  For example, on Intel x86
    platforms, the GNU <TT>gcc</TT> compiler generates function calls
    for the math library functions with <TT>-g</TT>, and also with no
    optimization option, but with <TT>-O1</TT> (or higher), it
    generates inline code to invoke Intel x86 hardware instructions
    directly.  The result of this is that with optimization, the math
    library, <TT>-lm</TT>, is not needed, and <TT>configure</TT> will
    set <TT>LIBS</TT> to an empty value in the <TT>Makefile</TT>,
    which will be wrong if you subsequently run <TT>make</TT> to
    compile without optimization.
  </P>

Another question is how autoconf is released.  For example, is version
2.49d an official release which can be safely used to replace 1.13?
