When the ghc-paths library is compiled, the paths of the
compiler it is compiled with are being hardcoded in the
library (and can then be queried from other applications
using the library).
But on Nix, packages are compiled with ghc-wrapper, and
subsequently possibly used with a special version of ghc
generated for a particular environment of packages. So
one version of ghc-paths may potentially end up being
used by lots of different instances of ghc. The hardcoding
approach fails.
As a work-around, we now patch ghc-paths so that it allows
setting the paths that can be queried via environment
variables. Specific GHC environments can then set these
environment variables in the wrapper shell script that
invokes GHC.
This should at least partially solve issue #213.
Replacing SBCL upstream tracking expression with a new version in a new
format.
Minuses: gave up on defining everything in Nix language (now update
expression is a series of actions to do when downloading fresh release,
it is actually interpreted by shell), now Nix expression contains
meaningful whitespace (the area to regenerate is determined by the
line with a specific comment and the closing brace on the otherwise
empty line).
Plusses: only one extra file which could even be moved out-of-tree if
desired, clean semantics for traversing multiple links (it is not found
in either Debian uscan or Gentoo euscan), the main expression is in one
file and is less different from usual style.
Any attempt to instantiate these expressions on an unsupported platform is
going to 'throw' an error. The call to 'assert' doesn't add any value to
that (and generates less readable error messages, too). Further details are
available at <https://github.com/NixOS/nix/issues/56>.
Previously, we installed std by omitting the tools directory. Now, there are
occasions where you actually want to use things like tools.haxelib from within
your project, for example to create something that interfaces with the haxelib
API. So we now just remove all files in there that were created during the main
build in postBuild.

Neko seems to think it is running in 32bit, even though it is compiled for
64bit. The fix is included in 1.8.3, which is not yet released as of now, so we
add a temporary fix until the release.

As well as for neko, we now have way less cruft within the mkDerivation
attribute set. We also now use make to build haxe, which will include haxelib
and haxedoc as well.
The main reason why I was doing this was because the package didn't build and
still was referencing mawercer.de, which does not contain those tarballs
anymore.
