Do you have any suggestions of where I should start?  The failures are with
tests that create preprocessed header file, remove the original header file,
then compile a program that includes the header file.  It fails to use the
preprocessed header file in that case and then fails because the
un-preprocessed header file no longer exists.  I can make it work by specifying
-ffreestanding, so does that mean that there is something in the system headers
that is inhibiting the use of preprocessed headers?

I am using the latest glibc and I do not see stdc-predef.h anywhere in my
install or object directories though I do see it in the glibc source directory.
