 This is a usability issue bothering me for a while, so I’ll write it down
 (and potentially attempt to solve it myself).

 Given `Imports.hs` with
 {{{
 import ABC
 import XYZ
 }}}
 with `ghc -c Imports.hs` I get
 {{{

 Imports.hs:1:1:
     Failed to load interface for ‛ABC’
     Use -v to see a list of the files searched for.
 }}}
 When I would want

 {{{

 Imports.hs:1:1:
     Failed to load interface for ‛ABC’
     Use -v to see a list of the files searched for.

 Imports.hs:2:1:
     Failed to load interface for ‛XYZ’
     Use -v to see a list of the files searched for.
 }}}

 Interestingly, with `-c` ghc reports (just) the first, with `--make`
 (just) the last import...
