[PATCH] hurd_types.defs: redefine io_statbuf_t, timespec_t and fsys_stat


From: Flavio Cruz
Subject: [PATCH] hurd_types.defs: redefine io_statbuf_t, timespec_t and fsys_statfsbuf_t as true structs
Date: Sat, 12 Nov 2022 02:19:45 -0500

time_t and long are defined as uint32_t or uint64_t depending on the
arch.
