	# Revert trap behavior for the sake of autoconf-generated configure scripts.
	# The problem here is that bash -c 'trap 0' works, but sh -c 'trap 0'
	# doesn't work because the bash developers are trying to adhere to POSIX in
	# that case.  Since all the configure scripts are #!/bin/sh, this breaks
	# them

	# Patch readline's bind.c so that /etc/inputrc is read as a last resort
