Been meaning to do this for years: introduce a configuration option

[u/mdw/putty] / mkauto.sh

#! /bin/sh
# This script makes the autoconf mechanism for the Unix port work.
# It's separate from mkfiles.pl because it won't work (and isn't needed)
# on a non-Unix system.

# Persuade automake to give us a copy of its install-sh. This is a
# pain because I don't actually want to have to _use_ automake.
# Instead, I construct a trivial unrelated automake project in a
# temporary subdirectory, run automake so that it'll copy
# install-sh into that directory, then copy it back out again.
# Hideous, but it should work.

mkdir automake-grievous-hack
