I don't have Windows right now.
I found out an easy way to test my development repository changes also under Wine.
Lazarus runs amazingly well with Wine.

I installed the latest Lazarus release Windows version on Linux. It opens with Wine automatically, no problems.
Then I ran a bash script (copied below and attached). It deletes the source directories and replaces them with symbolic links to my development sources.
Then I started the Windows version again. It complains about wrong version and a missing package but that is OK.
Then I rebuilt it from Tools -> Configure Build Lazarus ... and I have the latest Windows version of Lazarus running on Linux! Absolutely cool. :)
I can check that my changes don't break the Windows version already before committing them.

Why did not make symlink to just "LazDevelPath"? just made subfolders?

similar example from me:
My host is osx, linux os (14.04, 14.10, 15.04) on virtualbox. I didn't try use symlink for fpc and lazarus 'cos compiled units be in host (osx) they are trash for osx. I made "shared folder" in virtualbox to osx's "/opt/" folder. In linux, I made symlink for my projects and 2d party components's folders to under linux's "/opt/" folder, then made and build lazarus and test my projects sourse from (host) osx . I made all lpk (-FU) like this:
"../all_libs/lpkname/$(TargetCPU)-$(TargetOS)-$(LCLWidgetType)" my projects's as well. So no conflict.
I wish lazarus have to "environment options" for project and packages output directory

Because the standard installation puts FPC into the same folder. I wanted to use the already installed FPC. I could have installed Windows FPC under Wine separately of course but I didn't.

No conflicts here either. The compiled units go automatically to different directories, in this case to i386-win32 and x86_64-linux. I built from the Configure Build Lazarus dialog.

Good to hear. In the past there was one issue that some type of bitmaps were shown upside down. If you see a normal looking lazarus toolbar, then I think the issue is solved.

Yes, it is fixed.
I have now Manjaro Linux which has the latest versions of everything. Wine is 1.7.51-1.
