From 5296f6d315bdd8f1dc97348b788638327a6ab192 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Tue, 26 Jul 2011 16:08:35 -0700 Subject: h8300/m68k/xtensa: __FD_ISSET should return 0/1 Harmonise these return values with other architectures. In some cases this affects all compilers and in other cases non-gcc compilers only.
