Flake nix shells: Build fails when working directory path contains spaces

[FreaxMATE]

Describe the bug

Compilation of a c/c++ file fails in flake-based nix shell development environment when directory name contains spaces.

Steps To Reproduce

1. Create sample flake.nix and main.c in directory TestDir
flake.nix

{
  description = "Test";

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-24.11";
  };

  outputs = { self , nixpkgs ,... }:
  let
    system = "x86_64-linux";
  in {
    devShells."${system}".default =
    let
      pkgs = import nixpkgs {
        inherit system;
      };
    in pkgs.mkShell {
      packages = with pkgs; [
        gcc
      ];
    };
  };
}

main.c

#include <stdio.h>

int main(int argc, char**argv)
{
    printf("Hello world!");
    return 0;
}

2. Run nix develop
3. Compile the project using gcc main.c. This should run without issues
4. Now rename the parent directory name to Test Dir and run steps 2. and 3. again. This failed with:

/nix/store/vk4mlknqk9yjbqa68a7rvpfxfdw3rad7-binutils-2.43.1/bin/ld: cannot find Dir/outputs/out/lib: No such file or directory
collect2: error: ld returned 1 exit status

Expected behavior

Compilation should succeed without any error.
