Thomas

Thanks.  Happily, it has started working again now. I changed nothing!  Mysterious.

Hi Simon,

this doesn't look like a problem with the testsuite driver. The testsuite driver indeed calls 'diff', but has been doing so for years. Nothing changed there. I just ran the testsuite on Windows with msys2 to double check, and didn't get any framework errors either.

Something changed in your Windows setup maybe?

Cheers,
Thomas

I know that there have been recent changes in the testsuite stuff.  Could you fix please?
Thanks
Simon

Actual stderr output differs from expected:
'diff' is not recognized as an internal or external command,
operable program or batch file.
