Cygwin + Kannel

[David G. Navarro Ferrer]

Hi: 
I'm riding Kannel on Windows using Cygwin tools to emulate. When I run it tells 
me missing the libraries to compile C. Someone could tell me what is the 
specific library needs?, For I have installed all coming at the Cygwin site and 
did not work with any. 
Greetings.
