dnl CAUTION:
Do not put anything sensible here, like RODATA. That works with
dnl some Darwin tool chains, but silently breaks with other. (Note that
dnl putting jump tables in the text segment is a really poor idea
for many PC
dnl processors, since they cannot cache the same thing in both L1D and L2I.)
