Doesn't compile for x86_64_pc_windows_gnu

I get this error in an empty project with the only dependency being ring. gcc.exe is at C:\MinGW\bin which is in $env:PATH


PS C:\code\ring-test> cargo build

Something I noted when I tried debugging this issue myself was that curve25519.c doesn't seem to exist anywhere in the project file structure. The error produced by gcc is probably a missing file error.

To find the cause of your problem, I did the following:

I noticed that "sorry, unimplemented: 64-bit mode not compiled in" seems like the error to concentrate on.
I Googled "sorry, unimplemented: 64-bit mode not compiled in"
I found people discussing how this error is seen when MinGW is installed without selecting the "64-bit" option in its installer.

So, I believe if you reinstall MinGW and select the 64-bit option, you will get things working.

(curve25519.c is in crypto/curve25519/.)
