Mindaugas,
speed and size that's not all. We must also look at the quality.
Try run this code on different environment :

*----------------------
Function main()
local i, nd := 0.0, nd1 := 1.1
Cls
? nd
for i := 1 to 30
  nd := nd + nd1
next
for i := 1 to 30
  nd := nd - nd1
next

? nd
for i := 1 to 10000
  nd := nd * nd1
next
? nd, ValType( nd), nd > 0.000001
return Nil
*-----------------------

On OpenWatcom it is correctly executet, and on BCC (I do not know how
the MinGW) ?
