Cannot get layout of forward declarations! #202

Closed nwf closed 6 years ago

nwf commented 6 years ago

Building cheribsd 92646471565f4ac62286b905a22c53814e33ddef (and some changes that I don't think should matter), I get:

Nevermind; fixed already (by 4ec163fcae99416dad3644a38a9c322bc0c03978?)! Thanks. <3
