Yes, right. Sorry my mistake.

We got security bug report; it may be chance to switch -19. I put no
-fomit-frame-pointer .deb based on -18 at:
http://www.gotom.jp/~gotom/debian/glibc/2.3.2.ds1-18_i386.fofp/
I eliminate -fomit-frame-pointer from all architectures:
amd64.mk (nptl), i386.mk (nptl, i686), linux.mk (nptl-default),
s390.mk (s390x), sparc (sparc64, sparcv9, sparcv9b)
Also I remove -D__USE_STRING_INLINES from all architectures because I
suspect it has positive result for most people. The size difference
from the previous -18 is very small because it's affected only for
nptl and i686:
.deb .debsize(18) .debsize(ofp) e-size(18) e-size(ofp)

I think it does not break d-i size limitation. If you have no
David, Daniel, if you have no objection, I'll put it in -19.
