Summary: bits/cpu_defines.h not installed in freestanding mode.
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: dougk...@google.com
Headers like new and typeinfo include c++config.h, which in turn includes
bits/cpu_defines.h. However, the header bits/cpu_defines.h is not installed in
freestanding mode, causing problems. I believe the fix is to add cpu_defines.h
in the rule install-freestanding-headers of libstdc++-v3/include/Makefile.am.
