who can fix babel-french incompatibility with crossreftools

[Murray Eisenberg]

Is that a one-place code addition I need to make, or is it something I need to use to patch each and every command in crossreftools that uses the csname…endcsname construction?

[I _said_, in effect, that I’m nearly clueless so far as pure TeX is concerned(.I can get around OK with LaTeX constructs.)]
