help understanding the validate_build_xhtml failure of ./validate for my CPP patch

[Carter Schonwald]

Hey all, I'm trying to get my CPP_Setttings patch to validate,
and i'm trying to understand why my validate is failing. At this point im
stumped and I really could  use some help!

I'd appreciate some assistance digging into this,
the ticket in question is
https://ghc.haskell.org/trac/ghc/ticket/8683#comment:50

my current set of patches is
https://github.com/cartazio/ghc/compare/ghc:ghc-7.8...rb_cpp_settings(rebased
on top of current 7.8 branch)

and the confusing  error in question is

If someone could help me get to the bottom of this, I'd really really
appreciate it.
