Bug ID: 65902
Summary: GCC-5.1 fails to bootstrap for eCos/arm-eabi
Product: gcc
Version: 5.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libgcc
Assignee: unassigned at gcc dot gnu.org
Reporter: bernd.edlinger at hotmail dot de
Target Milestone: ---
build for eCos fails in libgcc because sys-include/cyg/infra/cyg_type.h
typedef's bool and libgcc/unwind-arm-common.inc defines it too.
