Subject: [PATCH] * apps/openssl.c: For VMS, take care of copying argv if
 needed much earlier,   directly in main().  'if needed' also includes when
 argv is a 32 bit   pointer in an otherwise 64 bit environment. *
 apps/makeapps.com: When using /POINTER_SIZE=64, try to use the additional  
 =ARGV, but only if it's supported.  Fortunately, DCL is very helpful  
 telling us in this case.
