Allow me to add that Cygwin is not a virtual machine in the sense of
WSL (Windows Subsystem for Linux), VirtualBox, etc. Rather, it consists
of a dll library that does a pretty good job mapping POSIX library
functions to Windows ones, and large collections of programs and libraries
that have been ported to the Cygwin environment, including X windows.
In any case, this means that it follows Windows linking conventions and
object formats.
HTH understand why tings are as they are.
