cabal repl (and nix build) do not respect <package>.buildinfo

[AleXoundOS]

Describe the bug
cabal build successfully builds the cabal project, which uses build-type: Configure with <package>.buildinfo and CPP definition in it.
But cabal repl fails:

$ cabal repl
Build profile: -w ghc-9.2.8 -O1
In order, the following will be built (use -v for more details):
 - cabal-buildinfo-example-0.1.0.0 (ephemeral targets)
Preprocessing library for cabal-buildinfo-example-0.1.0.0..
GHCi, version 9.2.8: https://www.haskell.org/ghc/  :? for help
[1 of 1] Compiling MyLib            ( src/MyLib.hs, interpreted )

src/MyLib.hs:6:14: error:
    Data constructor not in scope: MYDEF :: String
  |
6 | definition = MYDEF
  |              ^^^^^
Failed, no modules loaded.

Remarkably, nix build fails the same way!

To Reproduce
Steps to reproduce the behavior:

$ git clone https://github.com/alexoundos/cabal-buildinfo-example
$ cd cabal-buildinfo-example
$ nix develop
[devshell]$ cabal build
[devshell]$ cabal run
[devshell]$ cabal repl

Expected behavior
Generated <project>.buildinfo file must be respected in cabal repl (and nix build).

System information

• Operating system: tested on Linux (NixOS 23.05)
• cabal: v3.10.1.0
• ghc: v9.2.8

Additional context

This issue was already reported: #4195, haskell/haskell-language-server#3780.

This should have been fixed in #5573. Maybe there are some caveats and workarounds?

[mpickering]

I can see why this doesn't work, autoconfUserHooks doesn't set the preRepl hook. I will fix this.

What is the issue with nix build I imagine that is something different and probably related to nix packaging.
