236 * If we have 32-bit pointers everywhere, then we're safe, and

238 * above.)
239 * Problem 1: Compaq/HP C before V7.3 always used 32-bit
240 * pointers for argv[].
241 * Fix 1: For a 32-bit argv[], when we're using 64-bit pointers
242 * everywhere else, we always allocate and use a 64-bit
243 * duplicate of argv[].
244 * Problem 2: Compaq/HP C V7.3 (Alpha, IA64) before ECO1 failed
245 * to NULL-terminate a 64-bit argv[]. (As this was written, the
246 * compiler ECO was available only on IA64.)
247 * Fix 2: Unless advised not to (VMS_TRUST_ARGV), we test a
248 * 64-bit argv[argc] for NULL, and, if necessary, use a
249 * (properly) NULL-terminated (64-bit) duplicate of argv[].
250 * The same code is used in either case to duplicate argv[].
251 * Some of these decisions could be handled in preprocessing,
252 * but the code tends to get even uglier, and the penalty for
253 * deciding at compile- or run-time is tiny.
