Ah.  I think the problem is that some systems define quad to be a type
name (i.e., something like `#define quad quad_t').  This problem
showed up once before, so there is already code like this:

  #if defined (quad)
  #undef quad
  #endif

in quad.cc.  Things broke when some restructuring was done.  So, I
think the solution is to have mkbuiltins add a similar #undef to the
generated builtins.cc file.

Can you try adding those lines to the builtins.cc file by hand and see
if it solves the problem?  They should probably go just after
variables.h is included.

Thanks,

jwe
