How can I tell what versions of MinGW32 and MinGW64 (via Git Bash) I have installed?

Question

When I originally installed Git for Windows, I (somehow) ended up with two copies of Git Bash - one running MinGW32, one running MinGW64.

Given there's no command like mingw --version I could run, how can I determine what versions of these packages I currently have installed? I've been having some trouble with MinGW64 and wanted to see if there was a newer version available than what I have currently.

(For what it's worth, the latest version of MinGW64 for Windows appears to be 3.3.0 (source) although I'm not entirely certain whether I should be looking at the Win-Builds downloads or not - anyway, that's probably a separate question.)

To get the version, I've tried:

• Checking the icon context menu in each console window. MinGW64's options has an About window that says 'mintty 2.0.3'. mintty seems to be a terminal emulator for Cygwin (I also have Cygwin installed). MinGW32's properties doesn't seem to have a visible version number.

• Looking for a gcc executable in either of the terminal's bin's that I could run with the --version flag; neither of them have it (and I'm not sure either how tightly gcc is integrated with the terminal).

• Running sh --version. On MinGW64 I get version 4.3.42 of GNU bash, and on MinGW32 I get version 3.1.23 of GNU bash. However, I don't think this is the version number of the respective MinGW projects.

What am I missing?

uname -a

This is a common linux command to show the version info of OS.
