Because the configure script is trying to find them.
I suspect this is a program (or its configure script) which "thinks"
that Cygwin is Windows. (It appears to be testing explicitly for
winsock2.h; it shouldn't)

Tell the authors of the program that Cygwin is not Windows.
Take a look at config.log; it should contain the error message from
the compiler when it tried to use winsock2.h
Search for checking winsock2.h usability in
config.log; there should be a short C source, a gcc invocation and an
error message.
