I do not know what is "longjmp" method :-(

I do not have a DLL which wants to use the Win32 APIs. I have a
Linux dynamic library (*.so) which wants to use the Win32

What is "setjmp" - an assembler directive ? Is
<startwinelib.so> a standard WineLib application or I have
to create it myself ?

:-( What is "longjmp" exactly and how it should look like ?
Unfortunatelly I'm not familiar with the assembler too much, and
I know little about Wine :-(

Is LoadLibrary a Wine feature or Windows feature ?

This means that I link that magic <startwinelib.so> +
other Win32 libraries which I need (like -lavifil32) to
my Linux executable (or Linux dynamic library *.so) and
everything will work out of box ? But what is the key
point in this approach ? I do not use any functions in
<startwinelib.so> - just link it to my Linux application
and it will work ?!

Thank you very much.
