BTW, I just discovered that this was discussed in a thread beginning
11-30-2005 but never finished.

Anyway, your suggestion helps, but not quite enough.  The c code now
compiles and links okay into *.mod files, but now __enable_execute_stack
shows up in several und-*.lst files, so that moddep.lst won't build.

I cheated by copying moddep.lst from my linux machine, and that allowed
the build of grub to finish, but now I get that same missing symbol when
I *run* grub. <sigh>
