+++ This bug was initially created as a clone of Bug #1184732 +++ To get some testing we should enable rust for integration and nightly build for our 64-bit windows builds.

These patches are essentially the patches from bug 1184732, tweaked to only support win64. Repackaged upstream builds using bzip2. Builders don't seem to have xz.

Because of how subshells and exporting variables works with msys bash, we need to explicitly re-export everything interesting for things executed downstream from configure.

We can use the unix mozconfig.rust because it's generic.

The unix mozconfig.rust is actually completely generic now that we're using toolchains built with --enable-rpath in tooltool. Move the mozconfig.rust fragment up a level to reduce confusion.

Comment on attachment 8712680 [details] [diff] [review] part 3 - enable rust on win64 nightly builds. I think it would be a little more straightforward if parts 3 & 4 were swapped. ie: Make a common mozconfig.rust file, then use it in win64 configs.

Comment on attachment 8712681 [details] [diff] [review] part 4 - share mozconfig.rust between linux and windows Can we also remove build/macosx/mozconfig.rust? It has the same RUSTC & ac_add_options lines, but with a strange check for `uname -s` != Linux (which doesn't make a ton of sense in an OSX specific file).

That uname check is just a crappy hack to keep it from breaking the Taskcluster cross-compile builds :-/ I assume between froydnj and rillian there's enough knowledge on how to package a Linux rustc that can cross-compile to OSX now, so if we could get one of those in tooltool we wouldn't need that hack.

Making the cross-compile case work is next on my list of things to do, once these patches and bug 1177599 land.
