|
* 2011-03-22 SMS.
|
|
* If we have 32-bit pointers everywhere, then we're safe, and
|
|
* we bypass this mess, as on non-VMS systems. (See ARGV,
|
|
* above.)
|
|
* Problem 1: Compaq/HP C before V7.3 always used 32-bit
|
|
* pointers for argv[].
|
|
* Fix 1: For a 32-bit argv[], when we're using 64-bit pointers
|
|
* everywhere else, we always allocate and use a 64-bit
|
|
* 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[].
|
|
* The same code is used in either case to duplicate argv[].
|
|
* Some of these decisions could be handled in preprocessing,
|
|
* but the code tends to get even uglier, and the penalty for
|
|
* deciding at compile- or run-time is tiny.
