* Makefile.am, preinstall.am, libmisc/Makefile.am, wrapup/Makefile.am:
	Add the stringto family of string to number converters. These are
	error checking wrappers for the strtoXXX methods and do their best to
	return false if the conversion failed. The error checking required
	for this is tedious and error prone. Hence better to have in a family
	of helper routines.
