+     * duplicate of argv[].
+     * Problem 2: Compaq/HP C V7.3 (Alpha, IA64) before ECO1 failed
+     * to NULL-terminate a 64-bit argv[].  (As this was written, the
+     * compiler ECO was available only on IA64.)
+     * 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[].

+     * Some of these decisions could be handled in preprocessing,
