This LGTM (also in view of https://github.com/root-project/roottest/pull/1118, thanks for the test!), but is now marked as a Draft - what does this mean?

[pcanal]

It went to draft after I saw test failure that were tracked down to the missing write lock when changing the autoloading state. This has now been corrected.

[pcanal]

This fixes the run of roottest.root.meta.enums.execTEnumGetEnum on Windows (the roottest PR removes the will fail)

The failure on Windows was due to typeinfo(enum_type) returning a name with the format enum enumname and until the addition (in this PR) of the name normalization step, this was incorrectly handled by TEnum::GetEnum

The backport to v6-32-00-patches failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-v6-32-00-patches v6-32-00-patches
# Navigate to the new working tree
cd .worktrees/backport-v6-32-00-patches
# Create a new branch
git switch --create backport-15408-to-v6-32-00-patches
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 6219b6baba5d7e9602ba1790ee540c5fc0e2db0d
# Push it to GitHub
git push --set-upstream origin backport-15408-to-v6-32-00-patches
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-v6-32-00-patches

Then, create a pull request where the base branch is v6-32-00-patches and the compare/head branch is backport-15408-to-v6-32-00-patches.
