[Pkg-haskell-maintainers] Bug#641112: c2hs: FTBFS: hlibrary.setup: the following dependencies are missing: language-c >=0.3.1.1 && <0.4.0

[Aurelien Jarno]

Package: c2hs
Version: 0.16.3-1
Severity: serious
Justification: fails to build from source (but built successfully in the past)

c2hs version 0.16.3-1 fails to build, due to version mismatch. It
requires language-c <0.4.0, while the version in unstable is now
0.4.2.
