luckily, ghc does not have too many dependencies.

There are not many normal cases as ghc has few dependencies, and they
have not been renamed before :-)

Right, therefore I am suggesting it as a work-around only until we
managed to have ghc’s depending on libgmp-dev on all architectures. Then
you can remove the Provides.

I yet have to check if the current ghc packages actually work with
libgmp10-dev instead of libgmp3-dev, otherwise this work-around would
not help.

What would break? Other package build-depending on libgmp3-dev might try
to build and then fail (if they are hit by incompatibilities). But they
are not buildable now either, so while inconvenient, not a big problem. 

Any other possible consequence?
