Cargo: windows: note: /usr/bin/link: extra operand

[winks]

It seems like https://github.com/rust-lang/cargo/issues/2242 is (partially) back or at least shows the same symptoms.

I had 1.12 installed via the Installer on Windows 7, just upgraded to 1.15.1 (via rustup, it prompted me to install the Visual C++ Redistributable and I complied)

# preparation for repro
git clone https://github.com/winks/cerith
cd cerith
git checkout 27ca5f67f7880fc5806e7862413a9d1651562834

# I originally had 1.15.1, but downgraded, error output is the same, sans path names

OK, reinstalling and rebooting fixed it. Didn't look like a PATH issue, maybe it was. Sorry for the noise.

MinGW/Cygwin link.exe is run instead of MSBC link.exe. Placing MinGW/Cygwin after MSVC dirs will solve the issue.

While this may apply for some people, I don't have (and didn't have) Cygwin installed on this machine.

Here, Git's link was being used.

I had C:\Program Files\Git\usr\bin added on the System's PATH and C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Tools\MSVC\14.16.27023\bin\Hostx64\x64 on my User PATH.

In case anyone has this issue and there's no issue with PATH/rebooting does not fix it for them, reinstalling the Visual Studio build tools fixed it for me.
