Building C LDAP SDK using cygwin ONLY

Hi all,

I am trying to build the LDAP C SDK from Mozilla under cygwin 
and am looking for some advice.

The web page here:
    http://www.mozilla.org/directory/csdk.html 
lays out the steps to build the Mozilla C SDK from source. 

And, this page offers hints for building Mozilla for Windows:
    http://www.mozilla.org/build/win32.html#ss2.2b 

The issue is as follows:

    "The Windows build uses a UNIX emulator for Windows, cygwin,
    to control the build process, and command line tools from 
    Microsoft's Visual C++ to build its source files. "

I don't have Visual C++ and I would like to build this SDK 
using only CYGWIN tools.

FWIW: I need this to build the PerLDAP Modules for Perl.

Any built these tools without using MSVC++ components? 

Other useful advice? Thanks in advance ...
