 #define TARGET_HAS_HARDWARE_WATCHPOINTS
 
+/* Returns the number of hardware watchpoints of type TYPE that we can
+   set.  Value is positive if we can set CNT watchpoints, zero if
+   setting watchpoints of type TYPE is not supported, and negative if
+   CNT is more than the maximum number of watchpoints of type TYPE
+   that we can support.  TYPE is one of bp_hardware_watchpoint,
+   bp_read_watchpoint, bp_write_watchpoint, or bp_hardware_breakpoint.
+   CNT is the number of such watchpoints used so far (including this
+   one).  OTHERTYPE is non-zero if other types of watchpoints are
+   currently enabled.
+
+   We always return 1 here because we don't have enough information
+   about possible overlap of addresses that they want to watch.  As
+   an extreme example, consider the case where all the watchpoints
+   watch the same address and the same region length: then we can
+   handle a virtually unlimited number of watchpoints, due to debug
+   register sharing implemented via reference counts in go32-nat.c.  */
