test-failure in stackage nightly build about language-c

[lambdageek]

@visq I think this is happening because language-c.cabal doesn't include any of the files under test/harness/* as extra-source-files. So if you do cabal get language-c and then ls test/harness the only file that's shipped is run-harness.hs.

(Our .travis.yml doesn't test for that because it only does a cabal install from a source tarball, not a cabal build && cabal test && cabal install)

@bergmark
I see, thanks. We'll ensure the test works from the dist tarball and then I'll upload language-c 0.6.1 or 0.7.0.
@lambdageek
So extra-source-files should do the trick? It would be cool if travis.yml tested the dist tarball.

@lambdageek
Hmm, there is a lot that we would have to bundle for testing (examples, test framework, harness; I'm currently adding dg parse tests to the harness). I think it would be easier to disable the test if we are out of the source tree, and leave .travis.yml as is.

@visq I agree it's probably more expedient to have the harness disabled if running from a tarball - cabal doesn't make it easy to include a lot of extra source files, and while it would be nice to be able to test with a tarball, it would be a pain to maintain.
