It looks like two system include files are getting into a dogfight. You
might want to investigate whether you can reproduce the issue with a
smaller source file, possibly dropping some of the -I directories in
that cc command line, and submit the issue to the vendor if you get
convinced that the issue is not actually an R one.

If this is the case, your best hope is if you can make cc less picky
about such redefinitions.
