http://mail.gnome.org/archives/xml/2001-July/msg00000.html addresses a
minor nit with
http://mail.gnome.org/archives/xml/2001-June/msg00196.html. So, you
have :
  http://mail.gnome.org/archives/xml/2001-July/msg00002.html
  http://mail.gnome.org/archives/xml/2001-June/msg00196.html

I also think the patches address different problems.

I believe http://mail.gnome.org/archives/xml/2001-July/msg00002.html
is wrong for the following reasons (I have not tried it):
  1. Using AC_CHECK_LIB before AC_TRY_FUNC is just wrong. The
     fact that the library exists doesn't mean it should be used.
     Link with a library *only* if the function is not already
     found by linking with $LIBS (which AC_TRY_FUNC does).
  2. If you have both libiconv in /usr/lib and /usr/local/lib
     and you wish the one in /usr/local/lib to win, set
     LDFLAGS="-L/usr/local/lib" before running configure.
