This allows you to take one more thing out of the nm files and also lets targets that use watchpoints define it in their tdep file. cheers, Kris ChangeLog: 2003-02-24 Kris Warkentin <kewarken at qnx dot com> * target.h: (HAVE_CONTINUABLE_WATCHPOINT): define. (target_ops): add to_have_continuable_watchpoint. * target.c (update_current_target): add INHERIT line for to_have_continuable_watchpoint. * infrun.c: remove HAVE_CONTINUABLE_WATCHPOINT defines * config/i386/nm-i386.h, config/i386/nm-i386sco5.h, config/i386/nm-i386sol2.h, config/s390/nm-linux.h, config/sparc/nm-sun4sol2.h: HAVE_CONTINUABLE_WATCHPOINT defined as 1.
