I think the OP's problem is he knows no way to override the default and use only
the standard ./configure && make build approach. This seems to be explained
somewhat by running $ info autoconf "Site Defaults".

The OP could take a build config.cache and save it in /etc/config.cache, change
all -unknown-cygwin to -pc-cygwin, then create a shell script /etc/config.site
like:

# /etc/config.site for configure
#
# setup with export CONFIG_SITE=/etc/config.site in ~/.*profile
#
# Give Autoconf 2.x generated configure scripts a shared default
# cache file for feature test results, architecture-specific.
[ "$cache_file" = "/dev/null" ] && cache_file="/etc/config.cache"

then as noted above add "export CONFIG_SITE=/etc/config.site" to some
~/.*profile so it gets set up automatically.

He could also set up the script and cache files under $prefix/share/ for any
specific install targets, and not export CONFIG_SITE.

Or he could use cygport with the Cygwin source packages.
