Will do, sir.

Actually, FreePascal has no such limitation, it is
just that the calling convention is different than
Borland.

Any number of arguments can be passed to the library
from FreePascal, but they must be enclosed in a pascal
array:

curl_formadd( @firstpost, @lastpost,
[ opt_one, val_one, opt_two, val_two, CURLFORM_END ]
)

That is clean and simple enough (and it works) but it
makes the cross-compiler code look a bit strange:

curl_formadd( @firstpost, @lastpost,
  {$IFDEF FPC} [ {$ENDIF}
  opt_one, val_one, opt_two, val_two, CURLFORM_END
  {$IFDEF FPC} ] {$ENDIF}
)

I also have another option, to wrap the kylix/delphi
version in a function that takes the "array of const"
parameter,uses a switch-case on the size of the array,
and splits the elements into a "varargs" call.

That way I just have one BIG UGLY instead of a
bunch of little uglies. ;-)
