/* NAME
/*	sane_strtol 3
/* SUMMARY
/*	strtol() with mandatory errno reset
/* SYNOPSIS
/*	#include <sane_strtol.h>
/*
/*	long	sane_strtol(
/*	const char *start, 
/*	char **restrict end, 
/*	int	base)
/*
/*	unsigned long sane_strtoul(
/*	const char *start,
/*	char **restrict end,
/*	int	base)
/* DESCRIPTION
/*	These functions are wrappers around the strtol() and strtoul()
/*	standard library functions that reset errno first, so that a
/*	prior ERANGE error won't cause false errors.
