And as you noted in your follow-up message, the problem is the same on

Any suggestion on how to easily fix this?
If not, I have a utterly untested idea:
- Add a new helper function to t/ax/am-test-lib.sh that tells whether
we are running on MinGW or no (you can steal existing code from the
'require_tool()' function).
- Use it in cxx-demo.sh to determine whether we are running under
MinGW.
- If that's the case, use perl to normalize the line endings (turning
all CR-LF into simple LF).
Is this doable?
Thanks,
Stefano
