[fpc-devel] The usage of Include() doesn't work any more in 2.3.1

[Graeme Geldenhuys]

Hi,

-------------------------  snip  --------------------------
 Include(WindowAttributes, waStayOnTop);  // <== doesn't compile with FPC 2.3.1

 WindowAttributes:=WindowAttributes +[waStayOnTop];  // <== this does
-------------------------  end  --------------------------

As far as I understood, the above two lines should do exactly the same
thing and I have been using Include() since Delphi 5 days and FPC
2.0.2.  Now in FPC 2.3.1 it doesn't work any more. I get the following
error.

--------------------------------------------------

It compiles without issues under FPC 2.2.3 and prior.  What is wrong
with using Include() to add to a set?  I do it all the time, plus
WindowAttribute is a read/write property, unlike the compiler error in
2.0.4 where you could use Include() with a read-only property.  Is
this not a regression bug in FPC 2.3.1 maybe?

WindowAttributes are defined as follows:

...
  property WindowAttributes: TWindowAttributes read FWindowAttributes
write FWindowAttributes;
...
