PostgreSQL from source using MinGW

Hi, All.  

Has anyone successfully built PostgreSQL from source using MinGW?  Anyone have step-by-step instructions on how to do
this? I am willing to write the documentation on this if I can just get it to work.  :-) 

I have done the following:
1. Install MinGW
a. Go to URL:  http://www.mingw.org/download.shtml
b. Download:  MinGW-4.1.1.exe
i. Install full set of packages
c. Download:  MSYS-1.0.10.exe
i. Answer y/n questions (installed MinGW on "c:/mingw".  Make sure this is entered because you will not be able to
mountthe directory otherwise.) 
2.  Then, I ran "./configure"

However, I cannot get the make to work.  Do I still need to install the GNU Make utility?  Any suggestions?

configure: error: zlib library not found
If you have zlib already installed, see config.log for details on the
failure.  It is possible the compiler isn't looking in the proper directory.
Use --without-zlib to disable zlib support.

You need to run the 'configure' program first. See the file
'INSTALL' for installation instructions.
