Hi,
```
$ guix package -I gcc
gcc-toolchain 14.2.0 out
/gnu/store/x2kv3zw2k7ql211m5kvb6yw401gab0x9-gcc-toolchain-14.2.0
```
but nothing matches stdc++
```
$ guix package -I stdc\+\+
```
If I `guix search for stdc\+\+`, I get, libstdc++-doc 9.5.0 and 5.5.0,
texlive-stdclsdv, ocaml-stdcompat and rust-link-cplusplus. Is this
normal?
```

```
The only non-standard channel is my own, that only provides a couple
of packages. I doubt this is the culprit, as there is no gcc related
package and I was already experiencing issues before setting it up.
