Patch applied.

I'm starting to get a bit tired about anything related to compile testing.

It's not like I don't understand that it is good to test-build things ...

It's just that enabling this turns up so many strange compile bugs to
the left and right that it takes focus away from core development.
I don't know what can be done to alleviate the situation.

Yours,
