Reexporting is not the problem. The _using-declaration_ is.

Reproducer script:
```bash
#!/bin/bash
CXX=3Dg++
echo "mod2 mod2.gcm
mod mod.gcm" > mm.txt
echo "export module mod2;
namespace ns {
export int x =3D 0;
}" > mod2.cpp
echo "export module mod;
import mod2;
namespace ns {
export using ns::x;
}" > mod.cpp
$CXX -std=3Dc++23 -fmodules-ts -fmodule-mapper=3Dmm.txt -c mod2.cpp
$CXX -std=3Dc++23 -fmodules-ts -fmodule-mapper=3Dmm.txt -c mod.cpp
