I am >including here Solaris, DEC-Unix, IRIX. All vendors support old 32bit applications, but I expect with increasing difficulty. New 32bit applications is just a matter of deciding whether integers and pointers are 32 or 64 bits. time_t will still be 64 bit. I expect support for creating old type 32bit applications to be phased out within the next five years. I expect support for old type 32bit applications to be phased out within 10 years from now. I expect Unixes - even those which run on 32 bit systems - to be 64 bit (compliant) by the end of the decade. The reason for the disappearance will simply be that it costs money to maintain these environments. And it will be a long time since anybody created 32 bit applications which are not 64 bit compliant. I expect the y2k transition to have weeded quite heavily in the applications used. >Then you are definitely not quite up on things, given that >Linux most often is running on x86 machines which are 32-bits >by nature. It could still be a 64 bit operating system running on a 32 bit CPU. >Will the ia-32 have disappeared 30 years from now?
