mixing the uses of `configure' and `config.status' evaluation in a
single line.
Define `$SHELL' and use it.

single quotes in its argument.

Document --help=short and recursive.
Split the `Directory' section into `Installation directories' for
--prefix and --exec-prefix, and all the others into `Fine tuning

In the latter, don't repeat `in DIR', the user understands, and it
comes out better.
Default for --exec-prefix is PREFIX.
Reported by Kathryn Hargreaves.

the file does not exist, which may happen when a `configure' exits
brutally.

forbids members named like their hosting struct, so don't do it.
Use `#' to denote Autoconf comments, not `dnl'.
