Most of the strtoX functions have an _l variant, but one to watch is
atoi, which is defined with a hardcoded call to strtol, at least with glibc:
8<----------
/* Convert a string to an int. */
int
atoi (const char *nptr)
{
return (int) strtol (nptr, (char **) NULL, 10);
}
8<----------
I guess in many/most places we use atoi we don't care, but maybe it
matters for some?
