The header file 'windef.h' defines a structure named 'SIZE' - so if your
code includes either 'windef.h' or 'windows.h', then there would surely be a
problem with that code. But (I think) it would be the sort of problem that
prevents that code from even compiling, and there should at least be some
well-heralded warnings. Yet I gather the code is compiling ok, without
issuing any warnings.
Just thought I'd mention it ....
