[Lazarus] Custom options

[Michael Van Canneyt]

Hello,

What is the purpose of the 'all options' button in the 'custom options' page
of the project compiler options ?

It shows a treeview with what I assume are all available compiler options, 
and the treeview has checkboxes.

I would expect that checking an option would enter it in the 'custom options' page.

Instead, nothing happens. If I open the dialog twice, then the second time,
the options which I have checked, are no longer checked the second time.

Is this a bug ? I'm using a stock lazarus 2.0.6 on MacOS.

Michael.
