Configuring autoconf 2.69 and wget 1.12 fail

[gadi]

I try to build Autoconf and Wget on Windows Xp platform through Cygwin, but when I run the configure script for both packages, errors occur of the same bug:
[b] ./configure
configure: configuring for GNU Wget 1.12
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /usr/bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking build system type... configure: error: cannot guess build type; you must specify one
And I when I type ./configure --build=i686-pc-cygwin on the Cygwin console produce errors:
./configure --build=i686-pc-cygwin
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /usr/bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking build system type...
configure: error: invalid value of canonical build

Please, what should I do to configure scripts?
Thank you
