[Bug] Windows builds in CI fail

[wenzeslaus]

Describe the bug

OSGeo4W build in CI fails with many module builds failing, although many modules are built.

Error messages in the log are unclear to me because I see the same messages for modules which are working.

To Reproduce

Go to a recently opened or changed PR and see OSGeo4W check, e.g., #2448 or #2453. View raw logs.

• Operating System: Windows

The only way to find out would be to take the < /dev/null part here;

.../bin/g.copy.exe --html-description < /dev/null | grep ...

Since this might be easiest done directly in the CI which would require the temporary lifting of the direct edit restriction in the main branch.

[wenzeslaus]

No idea about the < /dev/null part, I can only say it is not > /dev/null.

But instead of lifting up restrictions for the main branch, you can simply try in a PR.

Fixed in #2508 and backported in #2510
