Comment (by vdelecroix):
Thanks very much (I am not at all a specialist but I need to call
char_max() in some constructor).
Is the following a safe test ?
{{{
sage: from sage.misc.limits import int_min
sage: int_min() # random (architecture and platform dependence)
-2147483648
sage: import sysconfig
sage: s = sysconfig.get_config_var('SIZEOF_INT')
sage: int_min() == - 2**(s*8-1)
True
}}}
Best,
Vincent
