`enable' and `disable' identifiers, because some platforms define in their system headers symbols with global scope that go by those names. * breakpoint.h (enum enable_state): Rename from `enum enable'. Also rename all the enum members to have the "bp_" prefix. (struct breakpoint): Rename the `enable' member to `enable_state'. (enum bpdisp): Rename all members to have the "disp_" prefix. * breakpoint.c: All users of `enum enable' and `enum bpdisp' changed. (args_for_catchpoint_enable): Rename the `enable' member to `enable_p'. All users changed. * tracepoint.h (enum enable): Remove. (struct tracepoint): The member `enabled' is now `int enabled_p'. * tracepoint.c: All users of the `enabled' member changed. * printcmd.c (struct display): The `status' member is now an int. * memattr.h (struct mem_region): Rename the `status' member to `enabled_p'. (enum enable): Remove. * memattr.c: Change all users of the `status' member of struct mem_region to use `enabled_p' instead. * infcmd.c (run_stack_dummy): Use disp_del instead of del. * go32-nat.c: Remove the kludgey work-around for conflicts between <dos.h> and "breakpoint.h". * tui/tuiSourceWin.c: Use disp_del instead of del. * tui/tuiSource.c: Use disp_del instead of del. * tui/tuiDisassem.c: Use disp_del instead of del.
