Setting LC_ALL to C helps keep gdb's output consistent ('print' gives us expected output). This fixes#17423. I do not have access to a windows/mac machines to test this. I've only tested it on an x86_64 linux box.
This PR adds a new Vim compiler file specifically for use with Cargo. It passes all arguments through, so commands like `:make build`, `:make clean`, and `:make run` all work as expected.
It also adds a quickfix autocommand for fixing the paths before populating the error list. `cargo build` reports errors with file paths that are relative to Cargo.toml, so if you're further down in the project tree, then trying to open the error will result in a blank buffer because Vim treats that path as relative to the working directory instead. With this fix, the paths work properly no matter where you are in the project.
Right now, libuv will **always** be built for the host system (at least when building on OSX) because the information about the cross compiler is never actually passed to GYP. I don't know how anybody has been managing to build cross compilers with this.
Note that, at least on OSX, there is a bug in GYP that will send clang flags to non-clang compilers and it will still attempt to use Xcode's libtool, so this doesn't completely fix the problem of cross-compiling on an OSX host, but it's a start.
When I fixed the previous issue with rational rounding, I had introduced a regression. There was also an overflow bug introduced for fixed-precision rationals. This patch corrects both bugs.
Because I'm still 😷😷😷 , I figured some mindless tasks would be better than trying to finish the ownership guide.
The manual has long been waiting for some ❤️❤️❤️ , and so I gave it a quick once-over. I made small commits in case any of the changes are a bit weird, I mostly did a few things:
1. changed 'manual' to 'reference.' I feel like this name is better. If it's not, It's not a huge deal. it shouldn't be `rust.md` though.
2. word wrapped everything appropriately. Changes 1&2 are in the first commit, so that its' easier to see the changes in the later ones.
3. fixed other small style issues
4. removed references to things that are in the standard library, and not the language itself
There's still lots of gross in here, but I didn't want to pile on too too many changes.

While reading the intro, I was confused as to why there were two variables named "numbers". Unless I'm mistaken and it's not necessary, let's get rid of it to make it clearer.
This breaks code like:
struct Foo {
...
}
pub fn make_foo() -> Foo {
...
}
Change this code to:
pub struct Foo { // note `pub`
...
}
pub fn make_foo() -> Foo {
...
}
The `visible_private_types` lint has been removed, since it is now an
error to attempt to expose a private type in a public API.
Closes#16463.
RFC #48.

The stability lint will now check code generated by macro expansion. It will allow to detect :
- arguments passed to macros using deprecated (and others) items
- macro expansion generating code using deprecated items due to its arguments (hence the second commit, fixing such issue found in libcollections)
Checking is still done at expansion, but it will also detect a macro explicitly using a deprecated item in its definition.
- Don't attempt to autoderef `!`. The `Deref`/`DerefMut` trait lookup would generate a bunch of unhelpful error spew.
- Don't allow explicit deref of `!`, since later passes just ICE. This closes issue #17373
- Don't allow explicit index of `!`, since later passes just ICE. There does not seem to be an issue associated with this
This is just true of all of Rust, and doesn't make a lot of sense now.
Especially as we move towards finalizing things, I think it's time for
this to go.
