/* 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.
