求Cygwin与GCC版本对应关系映射表及相关链接

Great question—unfortunately, there isn't a single, official public table that directly maps every Cygwin release to its corresponding GCC version. But there are reliable ways you can piece this information together on your own:

• Use the Cygwin Setup Tool: Launch the Cygwin installer (setup-x86_64.exe for 64-bit, setup-x86.exe for 32-bit) and switch to "View" mode. Search for the gcc-core package, and you can browse historical versions of the package alongside the Cygwin release cycles they shipped with.
• Check Local Setup Files: If you already have Cygwin installed, look at the setup.ini file in the /etc/setup/ directory. This file contains detailed version info for all packages installed with your current Cygwin release, including GCC.
• Dig Into Cygwin's Changelog: The official Cygwin changelog tracks major package updates across releases. While it doesn't list a direct 1:1 mapping, you can cross-reference release dates with GCC version updates noted there.
• Local Installation Testing: If you have access to older Cygwin installers, you can set up a test environment, run gcc --version in the terminal, and record the pairing yourself.

It's a bit manual, but these methods will let you build the mapping you need.
