That makes sense. However I know little about C and makefiles. When trying
to tun it, I followed the basic instructions (configure - make - "make
install") and got the above results. I have uploaded (hopefully) all
relevant files.

http://www.sencer.de/cygwin/configure.txt (~400kb)
http://www.sencer.de/cygwin/configure_log.txt
http://www.sencer.de/cygwin/make_log.txt
http://www.sencer.de/cygwin/make_install_log.txt

When executing `make` the following may be what is responsible for the
problem:
(See make_log.txt)

/bin/bash ../libtool --mode=link
c -Wall -W -O3 -Wshadow -pedantic -g -O2   -o mod_cgi.la -rpath
/usr/local/lib -module -export-dynamic -avoid-version cgi.lo  -lz
mkdir .libs
libtool: link: warning: undefined symbols not allowed in i686-pc-cygwin
shared libraries

An older post on this list is talking about sth. very similar:
http://www.cygwin.com/ml/cygwin/2003-08/msg00576.html

The problems seems to be that it is not actually building the shared objects
as requested, instead only spitting out static libraries. I tried the
proposed solution with: "-no-undefined" but that route didn't work, I ended
up with _WinMain AT 16 - errors.

How to proceed? TIA, much appreciated!
