Compile cygwin1.dll from source code

Compile cygwin1.dll from source code

[Biswapriyo]

I want to edit some code in cygwin1.dll for my project. So, I clone
git repository from this url:
git://sourceware.org/git/newlib-cygwin.git

I've gcc, g++, make installed with cygwin and mingw-w64 (and also in
WSL). But none of them generate DLL file. I also follow the commands
./configure & make. Command generates only object files. Is it
possible to compile cygwin1.dll from its source code?
