//! MSVC-specific logic for linkers and such.
//!
//! This module contains a cross-platform interface but has a blank unix
//! implementation. The Windows implementation builds on top of Windows native
//! libraries (reading registry keys), so it otherwise wouldn't link on unix.
//!
//! Note that we don't have much special logic for finding the system linker on
//! any other platforms, so it may seem a little odd to single out MSVC to have
//! a good deal of code just to find the linker. Unlike Unix systems, however,
//! the MSVC linker is not in the system PATH by default. It also additionally
//! needs a few environment variables or command line flags to be able to link
//! against system libraries.
//!
//! In order to have a nice smooth experience on Windows, the logic in this file
//! is here to find the MSVC linker and set it up in the default configuration
//! one would need to set up anyway. This means that the Rust compiler can be
//! run not only in the developer shells of MSVC but also the standard cmd.exe
//! shell or MSYS shells.
//!
//! As a high-level note, all logic in this module for looking up various
//! paths/files is based on Microsoft's logic in their vcvars bat files, but
//! comments can also be found below leading through the various code paths.
// A simple macro to make this option mess easier to read

// otherwise. If it is defined, then we find `link.exe` in `PATH and trust
// that everything else is configured correctly.
//
// If `VCINSTALLDIR` wasn't defined (or we couldn't find the linker where
// it claimed it should be), then we resort to finding everything
// ourselves. First we find where the latest version of MSVC is installed
// and what version it is. Then based on the version we find the
