It turns out it's not broken if the build system is autodetecting an
MSVC install (as in, if it's registered in the Windows registry).

It is broken if it's not, and bug 1523540 should fix that.

Actually, that, as well as --target=aarch64, announced in
https://groups.google.com/d/msg/mozilla.dev.platform/F8VOvJHP1T0/tXJ7ldeVDAAJ

is likely broken at the moment. Thankfully, that will be fixed with bug
1523540.

PSA: 64-bits Windows build are now the default on 64-bits Windows

2019-01-28 Thread Mike Hommey
Hi,

As of bug 1522354, now on autoland, hopefully merged in a few hours,
the default build you get on a 64-bits Windows machine will be 64-bits,
instead of 32-bits like it had been forever.

If you do wish to do a 32-bits build on a 64-bits Windows machine, you
can add:

```
ac_add_options --target=i686
```

to your mozconfig, and that will do it.

Cheers,

Mike
