The packages within the MinGW/Base directory are supported by the MinGW
team and provide the core facilities required for a basic MinGW
installation.
To install files distributed by MinGW we suggest you use the mingw-get
installer https://sourceforge.net/projects/mingw/files/Installer/ and
you can choose mingw-get or mingw-get-inst. Mingw-get-inst is a wrapper
for mingw-get using InnoSetup, more can be found in the mingw-get-inst
README file.
