Downgrading Cygwin

Last week I was trying to set up an OpenJDK build environment on my Windows 11 machine. Building the repo would fail due to segfaults when running make. The workaround is to downgrade Cygwin from 3.3 to 3.2:

1. Launch the Cygwin setup program (setup-x86_64.exe).
2. Change the View dropdown to Full.
3. Enter cygwin into the search box then select the cygwin package..
4. Open the cygwin package’s dropdown in the New column.
5. Change the selection from Keep to the desired version as shown in the image below.

6. Click on the Next button then verify that the downgrade is to the desired version.

Finish the setup process then launch cygwin and verify that the version is correct by running:

cygcheck -c Cygwin
