  Portability problems fixed by Gnulib:
  @itemize
  @item

  @item
  This function does not allow for a NULL @samp{resolved} parameter on
  some platforms:
  Mac OS X 10.5, FreeBSD 6.4, OpenBSD 4.4, Solaris 10.
  @item
  This function does not always return an absolute path on some
  platforms:
  Solaris 10.
  @item
  This function fails to detect trailing slashes on non-directories on
  some platforms:
  glibc 2.3.5, macOS 11.1, OpenBSD 6.0.
  @item
  This function fails to recognize non-directories or symlinks to non-directories
  followed by @samp{..} on some platforms:

  @item
  This function misbehaves on consecutive slashes on some platforms:
  musl libc 1.2.2, AIX 7.

  Portability problems not fixed by Gnulib:
  @itemize
  @item
  This function does not allow to determine the required size of output buffer;
  the use of a non-NULL @samp{resolved} buffer is non-portable, since
  PATH_MAX, if it is defined, is nothing more than a guess.
  @end itemize
