I am not entirely sure I have got everything right, but if it compiles it is ok probably...
I tested it with msvc x86_64 and gnu.
Somehow a lot of `EXCEPTION-*` constants are dead code when running test, no idea why.
I have put `#![cfg_attr(test, allow(dead_code))]` at the top for this.
The MinGW-based Python implementations would automatically do this, but if we
want to use Python from the official downloads our usage of `/` instead of `\`
can wreak havoc. In a few select locations just use `os.path.normpath` do do the
conversions properly for us.

I'm a bit iffy on the return type, but `Result` would also be a bit weird... The two error cases are `Unterminated` and `InteriorNul(usize)`.
I considered `from_chars(&[c_char])` but this meshes better with `as_bytes_with_nul()` and Rust code in general.
Should there also be a corresponding unsafe `from_bytes_unchecked` variant?
`ReadFile` and `WriteFile` take a DWORD (u32) for the length argument
which was erroneously cast from a usize causing truncation. This meant
methods like `write_all` and `read_exact` would unexpectedly fail if
given a buffer 4 GiB or larger.
We can instead just ask for `u32::MAX` bytes if the given buffer is too
big.
The `vfp2` option was a leftover from `armv6` compatibility features of the original armhf target.
Gcc defaults to `vfp3`on `armv7` hard-float linux systems so we should make it the default for rustc too.

Hello.
I came across some minor spelling mistakes while going through the documentation for the `Iterator` trait. Also includes a suggested styling fix.

The standard library doesn't depend on rustc_bitflags, so move it to explicit
dependencies on all other crates. Additionally, the arena/fmt_macros deps could
be dropped from libsyntax.
Android should use 64-bit LFS symbols for `lseek` and `ftruncate`, lest
those offset parameters suffer a lossy cast down to a 32-bit `off_t`.
Unlike GNU/Linux, Android's `stat`, `dirent`, and related functions are
always 64-bit LFS compatible, and `open` already implies `O_LARGEFILE`,
so all those don't need to follow Linux. It might be nice to unify them
anyway, but those other LFS symbols aren't present in API 18 bionic.

Some struct members have a slighty different name on NetBSD. This has been fixed in the libc crate, but not in libstd, breaking the NetBSD build. Related C struct definition: http://nxr.netbsd.org/xref/src/sys/sys/stat.h?r=1.68#59
This also removes the broken `st_spare()` from MetadataExt, since it is private field reserved for future use.
@dhuseby In case this conflicts with any of your pending patches, feel free to intervene - I'm happy to withdraw this PR.

With these changes you can build a freestanding sysroot without using floating points using a Cargo.toml and copying the `deps` folder cargo outputs.
```
[package]
name = "sysroot"
version = "0.1.0"
[lib]
path = "lib.rs"
crate-type = ["rlib"]
[dependencies.core]
path = "../vendor/rust/src/src/libcore"
features = ["disable_float"]
[dependencies]
collections = { path = "../vendor/rust/src/src/libcollections" }
```

Tracking issue: #31756
RFC: rust-lang/rfcs#1467
I've made these unstable for now. Should they be stabilized straight away since we've had plenty of experience with people using the unstable intrinsics?
This warning was introduced on Nov 28, 2015 and got into 1.6 stable, it was later requalified from a hardwired warning to a warn-by-default lint.
If this patch is landed soon enough, then `match_of_unit_variant_via_paren_dotdot` will get into 1.8 stable as a deny-by-default lint.
My intention is to turn it into a hard error after March 3, 2016, then it will hit stable at 1.9.
