doxygen 1.10.0 problems

In a local conda env with doxygen 1.10.0 I get the following warnings, treated as erros, from building or testing doxygen:

make[2]: Entering directory '/home/dkeitel/git/lvc/lalsuite/conda-lalsuite-dev/lal/doxygen'

I'll put an MR for the "subsection" imminently; for the other "iline" issue I have no immediate idea what it's talking about.
