[rc1 tarballs] configure help error and a few warnings

["Marcelo de G. Malheiros" <mgm valedofuturo unicamp br>]

  I just compiled the RC1 tarballs in a standard GNU/Linux system and
everything went fine, except for minor errors in the "configure
--help" texts (missing default values) and a few warnings, listed
below.

  System: Conectiva Linux 7.0, Kernel 2.4.12, XFree86 4.0.3, gcc 2.95.3
          export CFLAGS="-O -pipe"

  Congratulations to all developers for such great work!

  Regards,
    Marcelo Malheiros
