* rs6000-tdep.c (single_step): Don't call ptrace, we are a
high toned routine. Fix return type to void.
+ * tm-rs6000.h (AIX_BUGGY_PTRACE_CALL): Zap, we think we fixed it.
+ Rich and I believe the "real problem" was that both single_step
+ and target_resume were issuing PT_CONTINUE calls. This would
+ cause the second PT_CONTINUE to sometimes fail because the process
+ was already running.
+ * infptrace.c (child_resume): Remove AIX_BUGGY_PTRACE_CALL kludge.
