This is strange: they copy explicitly goes into $(gcc_objdir): from
libgcc/Makefile.in:
install-unwind_h:
cp unwind.h $(gcc_objdir)/include/unwind.h
chmod a+r $(gcc_objdir)/include/unwind.h
For an in-tree build, the source directory cannot be read-only, for a
VPATH build I don't see how this can happen. Could you please check?
Thanks.
