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" }
```
