Comment (by artyomtnk@…):

 The problem is that VMS allows mixed 32 and 64 bit pointers (something
 like DOS's near/far) and some system functions - in this case
 localetime_r, accept only 32 bit pointers while most accept both type of
 pointer.

 What happens is that I need to pass 32 bit pointer to the function to make
 sure
 it works. Result is 64 bit pointer so I can't pass it as is. So I create a
 local variable
 tmp that is placed on stack. And it is promised that stack is always
 placed in 32bit region so I can relate on the fact that the pointer would
 be 32bit pointer.

 And after I get the result I can copy it to the location of 64 bit
 pointer.

 This is quite ugly but that is how OpenVMS works.

 Thanks,
   Artyom
