Hmm, on thinking about this more, there are probably existing Linux machines where glibc canonicalize_file_name is broken (fails to detect ENOTDIR on "file/"), and therefore we need to replace it. Additionally, it would be nice to declare canonicalize_file_name in <stdlib.h>. Also, now that POSIX requires realpath(name,NULL) to malloc() its results as an absolute path, it would be nice to have a realpath module that replaces broken versions (Solaris sometimes gives relative paths, and not all existing realpath implementations malloc). -- Eric Blake
