`gcc-14.3.0` will likely release around the end of April
(https://gcc.gnu.org/develop.html) which is a bit late for
nixos-25.05 release.
We can update to `gcc-14.3.0` after a branch-off, but let's
make the delca smaller by picking the current snapshot.
While at it:
- fix `flex` dependency propagation and use it for snapshots
- fix `version` to always contain the base version as
cc-wrapper constructs paths to libraries based in `version`

After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.
Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.
A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.

Release branch from 6½ years ago, no update in 3½ years, unsupported
upstream, and unused in tree.
This finally resolves the tangled conditionals in `all.nix`, albeit in
a way I assume amjoseph wouldn’t have been too fond of. `default.nix`
still has some gnarly stuff in there. So it goes…
The stable release has too many AArch64 issues, but they seem to
have been fixed upstream; Arch is shipping a Git snapshot. The next
stable release should be out by the time 25.05 is finishing up,
so this should be okay as a temporary solution.
This is the GCC 14-20241116 snapshot. We use that identifier as our
package version, diverging from our usual unstable version convention,
because it identifies itself as “gcc (GCC) 14.2.1 20241116” and
comes in `gcc-14-20241116.tar.xz`; 20241116 is therefore a useful
version identifier to use verbatim, and 14.2.0-unstable-2024-11-16
would potentially be confusing for a version that calls itself
14.2.1. The next stable release from the GCC 14 branch will be 14.3.0,
so there should be no ambiguity here.
Getting this version is a little complicated; we need the precompiled
`flex(1)` output that these Git snapshots don’t include. Thankfully,
the source file hasn’t changed since 14.2.0, so we can simply
download 14.2.0 too and extract the precompiled file. A little
merging finesse is required for the `aarch64-darwin` patch, which we
also upgrade.
gcc-4.9.4 was released in Aug 3, 2016, 8 years ago. It's a branch that
went out of support years ago. Numerous bugs never get backported to
this version.
Let's remove it.
gcc-4.8.5 was released in June 23, 2015, 9 years ago. It's a branch that
went out of support years ago. Numerous bugs never get backported to
this version.
Let's remove it.
