Hi Richard,

In addition to causing the bootstrap failure on x86-linux, this patch
also causes bootstrap to fail on powerpc-linux.  Please also note the
regressions on powerpc-eabisim.

Also, your subsequent change to dwarf2out.c has no ChangeLog entry;
please add one.  (It doesn't fix the bootstrap problems either.)

On what platform did you test your dwarf2out.c changes?
