The only reason to include <term.h> in sysdep.c is to get a prototype
for `tputs' (used in `reset_sys_modes') .
cm.c also uses tputs, but it adds an extern declaration for it.

Given that including <term.h> seems to cause problems, maybe a good
workaround would be to move `reset_sys_modes' to cm.c.
