Static linking of CRT for Windows

We now have to debug why rustc is failing. See the config.

@syxolk Could you dig into this please? I don't have a Win box at hand.

It worked like this:

rustup default nightly
set "RUSTFLAGS=-C target-feature=+crt-static"
cargo build --release

Running dumpbin.exe /dependents target\release\indentex.exe leads to this output:

Dump of file target\release\indentex.exe

File Type: EXECUTABLE IMAGE

  Image has the following dependencies:

    KERNEL32.dll
    ADVAPI32.dll
    USERENV.dll
    SHELL32.dll

  Summary

        2000 .data

        9000 .pdata
       59000 .rdata
        2000 .reloc
      17B000 .text

Compare to this output without RUSTFLAGS:

It explicitly didn't work for:

• Rust stable
• set RUSTFLAGS='-C target-feature=+crt-static' (note the placement of quotes)

Using the nightly-x86_64-pc-windows-msvc toolchain:

Build type	With RUSTFLAGS	Without RUSTFLAGS	diff
release	1910 KB	1823 KB	+87 KB
debug	6474 KB	6384 KB	+90 KB

Oh, the quotes in Windows command line... I've got bitten by them several times before and should have known better.

And I'm very surprised that it didn't work for stable Rust, it's really weird. However, I'm ok with using nightly for building Windows installs.

Nice! https://ci.appveyor.com/project/mp4096/indentex/build/job/ej1lgmg8l411r6xu

@syxolk Could you please refactor your current script to PowerShell and add a compilation command to it? Cf. the AppVeyor config.
