New description:

 This is due to a trivial programming error.  I already have an spkg fixing
 this, along with a moderate clean-up of the spkg.

 See #12751 for the GCC-4.7.0 metaticket.

 Well, these have been in before (and the respective files were of course
 user-readable, and they don't get installed anyway).

 Anyway, fixed; new spkg, same place.
