 I have removed -fglasgow-exts from the line

 Ghc-Options:  -Wall -fglasgow-exts

 of my .cabal file, but otherwise no file did change.

 After that I was told to

 ./Setup.lhs configure

 and then

 ./Setup.lhs build

 The latter did not complain.

 Then I did:

 ./Setup.lhs clean

 and

 ./Setup.lhs build

 This time I ended up with compile errors.

 (Unfortunately I uploaded the package to Hackage before noticing this :-(

 The right way to fix this might be to (configure to) remind the user to
 clean
 the package before building (or to do that automatically).
