What happened was, I prematurely created directories named libfeutil
and libfeutil/include in the CVS repository, then changed my mind and
deleted them - but the only way I know how to delete a directory in
CVS is to go into the repository and rmdir it by hand. Since I never
checked anything into these directories, I thought this would be
harmless, but it seems I was mistaken.
There's now a libcpp and libcpp/include which may get the same
treatment, because Ben wants it called libpp. (I'd really appreciate
some opinions on what this directory *should* be called. It is mostly
cpplib, but it's getting a number of pieces of common functionality
too, like line-map.c and hashtable.c.)
