[fpc-pascal] Re: build a compiler for GO32v2 under Windows 8 (or 7)

[Philippe]

I really assumed that I had to choice between video unit and crt
unit ... 

my old unit which interfaced the video must be updated to be
compiled for win32. 

I already though about to create my window
procedure and my gotoxy procedure ... this way I may not have to make a
lot of changes in my program. 

I missed SetCursorPos ... thanks a lot


My first step, anyway, is to verify it is compiling for win32! ...
later I´ll make more changes and all the adjustments.
