No, I do not see any such warning.  This explanation appears unlikely as
it had no problem building every other cpp file.

There is a third alternative:  have someone fix whatever broke in the
last week or two.

And, no, I cannot use llvm-i386.cpp or llvm-rs6000.cpp as I am running
x86_64.  Nor am I going to debug the gcc build system.
