mingw-get "upgrade all"

Introduction

MinGW includes a utility, mingw-get which is a simple package manager for the MinGW distribution. Unfortunately, there is no "upgrade all" option. So, how to upgrade all installed packages?

Command line

mingw-get upgrade $(mingw-get list | awk '$1=="Package:" && $3=="Subsystem:" && NF==4{print $2}')
