every test dies: "changing search order for system directory"

Subject: every test dies: "changing search order for system directory"

My mainline cross-compiler to powerpc-eabisim is failing the library
testsuite because of "excess errors" on every test:

cc1plus: warning: changing search order for system directory "/home/pme/build/B/powerpc-eabisim/newlib/targ-include"
cc1plus: warning:   as it has already been specified as a non-system directory
cc1plus: warning: changing search order for system directory "/home/pme/src/unified/newlib/libc/include"
cc1plus: warning:   as it has already been specified as a non-system directory

I'll give the compile line below, but I'm confused why others aren't
seeing it.  (I'm also confused why the regression tester fails with an
error message that I can't reproduce on this same target.)

help?

Phil
