Do I need to find an older version of rust?

[frg]

Either use 1.73.0 or use this patch:
https://bugzilla.mozilla.org/show_bug.cgi?id=1896958

We can't put it in. Rust is crap:

- Rust 1.74 dropped support for macOS 10.11 which we still support.
- Rust 1.78 dropped support for Windows 7 and 8.1. It added a tier 3 compile target for these versions but this is currently more or less unsupported and untested. Server 2012 R2 is still supported with ESU patches for about 2 years and would be affected by this too.

I managed to track down rust 1.77.0, deinstalled 1.81, waited an eternity for 1.77 to compile and ... SUCCESS.

I've saved the rust 1.77.0 tarball for the next time as it took me ages to track down the old FreeBSD port.

Thanks!
