That is correct. When you try to build windows application in the
MinGW project, often times you need to run a configure script that may
require tools that don't have native windows versions. The way MinGW
helps these configure scripts run is by taking advantage of the the
MSYS2 environment -- which is similar to Cygwin -- so that has enough
tools to run a configure script.  It includes a version of Guile for
the purpose of running configure.

Like Cygwin, MSYS2 also has a big library that emulates POSIX that
everything links to.  The difference betwen MSYS2 and MinGW is that
MinGW apps try to link directly to windows libraries without linking
to an emulation library.
