        * Makefile.in: Regenerated.

already. I think the issue is that while both libcpp/configure of 20081016 and
20081026 are
properly setting CPPFLAGS in the libcpp/Makefile, after your changes setting of
CPPFLAGS now
also occurs in the toplevel Makefile and that is being used instead of the
setting of CPPFLAGS in 
libcpp/Makefile. Notice even though the build fails in current gcc trunk, if I
go into the libcpp
and execute make the problem doesn't occur because CPPFLAGS is defined properly
in that 
Makefile and the toplevel Makefile doesn't get a chance to override it.
