The output files are kind of hard to read separated into results and
errors since it's not clear what generated the errors.  You might try
  ./configure ... args ...   >output.txt 2>&1
which will write stdout and stderr to output.txt as one results.
(at least on unix, I guess cygwin will do the same).

yeah, I've changed the configure so some of the remaining benign
warnings will not appear.

checking Python includes... -I/usr/include/python2.3

How shared libraries (dlls) work under cygwin or even win32 is not
something I know about.

Looks the same problem here - where does it look for dlls?

You might try copying the resulting files from the perl or ruby dirs
into wherever the installed perl and ruby install to.

the configure says:

checking Python includes... -Ic:\Python23/include/python2.3
checking Python libs... c:\Python23/lib/python2.3/site-packages

which I guess is right.

But this clearly isn't working, from the errors:

...
Redland_wrap.c:13:20: Python.h: No such file or directory
Redland_wrap.c:234:20: Python.h: No such file or directory
Redland_wrap.c:283: error: syntax error before "PyObject"

which presumably is from the line:
gcc -DHAVE_CONFIG_H  -I..    -DLIBRDF_INTERNAL=1 -g  -fPIC -DPIC -I../librdf -I../librdf/ -Ic:\Python23/include/python2.3 ./Redland_wrap.c -c -o Redland_wrap.so
Maybe cygwin or gcc gets confused with that mixture of DOS and unix
names.

Well it didn't compile the Redland_wrap.so, so it's not likely to
work. Probably the .so name isn't correct for cygwin, should be
.dll or something.

As you can guess, portable shared libraries are a pain.  libtool
is a helper but it has it's own problems.
