+ * Problem 2: Compaq/HP C V7.3 (Alpha, IA64) before ECO1 failed

+ * Fix 2: Unless advised not to (VMS_TRUST_ARGV), we test a
+ * 64-bit argv[argc] for NULL, and, if necessary, use a
+ * (properly) NULL-terminated (64-bit) duplicate of argv[].
+ * The same code is used in either case to duplicate argv[].
