Nope, but a compiler should choose the_optimum_ for the platform. 
Otherwise you can hand-code it.
The A/W versions of the windows API have been in Delphi at least since 
D3, but I can check D2 in a minute.
Of course it's a compile time switch! Point made by me in the first place.

BTW you can even fool delphi and fpc to behave irratically (do what I 
want)  by doing things like -uFPC -Mdelphi -dVER200 in fpc or defining 
-dVER200 when you have a D7 (VER150) .
  Sometimes handy to know the compilers (be it C or FP-C) at least 
understand the programmers meaning.
(Just in case you wonder why I would fool the compiler to be over his 
age: parsing some badly behaving sourcecode)
