[fpc-pascal] uses myunit in '../src/myunit.pas' ?

[Tim Veldhuizen]

Indeed, I can confirm Delphi does this. I think since 2009 or XE or so, 
but AFAIK it doesn't need to. It does it only for the files that are 
explicitly added to the project, but those are also in the dproj file. 
And it would compile just fine without explicitly referring to the files 
in the dpr file, so I'm not exactly sure why it does it. Perhaps it's a 
kind of optimization for the caching system in the IDE..

For units that contain a form, there is also the name (value of the name 
property, not the classname if I recall correctly) of the form in curly 
braces comment behind the file reference and it seems the IDE does 
something with that as well. I can't remember clearly, but I recall an 
odd anomaly in a big application with lots of legacy that had something 
to do with such a comment for a unit with a form.
