Your second point explains the first.
cygport attempts to detect the version of autoconf used to generate the
./configure script, so it knows what options it supports.
If that detection fails (as in this case, because it's generated by
customized version), you can set AUTOCONF_VERSION appropriately.

2.
configure: error: unrecognized option: --docdir=/usr/share/doc/xterm
This seems to be injected by the cygconf function, and the package
configure script does not know it.
For configure files generated by dickey's variant of autoconf, the
correct thing seems to be to use AUTOCONF_VERSION="2.50"
