- * Added improved VMS support from Pat Rankin:
+ Added improved VMS support from Pat Rankin:
+
+ Fri 19 May 16:51:40 1995 Pat Rankin (rankin@eql.caltech.edu)
+
+ * config/obj-vms.h (AOUT_STABS): Define.
+
+ * config/obj-vms.c (fpush, rpush): New routines.
+ (push): Replaced by the above.
+ (find_symbol): Slight reorganization to expose tail recursion.
