Not really interested in DOS, big issue is, even in TP-mode, that FPC does not 
honour the old TP construction where all variables in a single var/const 
declaration are kept in the final executable, i.e. I use

const
   xxx_ptr : xxxptr  = nil;
   xxx_top : xxxptr  = nil;
   xxx_end : xxxptr  = nil; {or, occasionally @xxx_top}

and update them after an insert in the linked list with a small assembler 
routine that never explicitly uses xxx_end, nor do I ever explicitly use xxx_end 
myself and that results in FPC eliminating it. VP sticks to the Borland 
implementation!

Next to that, but that's resolvable, I don't like records to be non-packed, or, 
more in general, that FPC "wastes" too much data by auto-aligning variables on 
"preferred" boundaries and that it can reorder the location of variables that 
are not part of records.

And I really like that I can directly call VP RTL functions from my inline 
assembler code, without having to figure out name-mangling.
