Roger, I used MinGW candidate using the Automated MinGW Installer:

http://sourceforge.net/project/showfiles.php?group_id=2435&package_id=240780

Only installed the C compiler (do not install make since will clash and 
do weird things).

Installed MSYS-1.0.10 and MSYS DTK.

Then I followed the steps to install MinGWports and installed as ports 
readline and zlib

(Zlib is official, readline is a patch in the tracket at sourceforge).

I unzipped the ruby package and run inside a MSYS console:

./configure --with-winsock2
make

At this point you should check the output for 'compiling readline' 
'compiling zlib' etc... and see if everything worked.

make check (to run tests)
make install

That will create bin/lib/man/share in the root of your drive (thats 
because generated make file isn't compatible with MSYS).

You should have there a working implementation.

zlib.dll will be located at you MinGW bin folder, which is where 
MinGWport install it.

The same for readline.

Write this mail from memory took me a few minutes, but compile with VC8 
(replying your other mail) is more complex.

I could give you a full checkout of my own repo where I was hacking 
this.

Contact me off the list if you're interested.

Regards and hope this help,

Luis
