Wow. 8 hours. I take it that you are bitten by the same issue as Git for
Windows, where Git's test suite uses Unix shell scripting rather heavily,
and Unix shell simply requiring tons of expensive emulation to run
decently on Windows.

How automated is your process? (Including, most importantly, updating
the Cygwin build setup...)

I ask because I could possibly set up something using the existing
infrastructure for Git for Windows' testing, as long as

1) everything is scripted, and

2) you do not need interactive access to any box (I mainly use Docker
   containers to run the builds)

If you are interested, feel free to ping me via private mail.

Ciao,
