Subject: [ruby-core:59514] Re: [ruby-trunk - Bug #9352] [BUG] rb_sys_fail_str(connect(2) for [fe80::1%lo0]:3000) - errno == 0

Thanks for testing.  I can't say I like my patch, however, as
it's still error-prone and fragile.

How about some new functions to the C API:

	rb_syserr_fail_str(VALUE mesg, int errnum);
	rb_syserr_fail(const char *mesg, int errnum);

And deprecate rb_sys_fail and rb_sys_fail_str.
