Compiling Rust with GCC: an update

It may not be better but it is more accurate. Even if one were to stick to the same conclusion they had originally, it's helpful to validate the data points. The common narrative appears to be that GCC support for various languages including Rust are being added based on unreasonable demands for some unknown but definitely odd reasons and they will inevitably fail or splinter the language and the spec based approach is an old relic of the past that must be inherently doomed one way or the other. It doesn't leave room much room for acknowledging that multiple languages do have several successfully used implementations or even a mild curiosity of why things like gccrs is even funded by commercial organizations in the first place.

> I don't hate the idea of multiple implementations, but it really gives reason to temper your expectations of what gccrs will deliver.

This is something readily acknowledged in https://github.com/Rust-GCC/gccrs/wiki/Frequently-Asked-Q... but this is some extend mitigated by funding and possibility of code sharing via things like polonius.
