The compiler does not do anything special: it determines its current 
working directory using the RTL, meaning it gets the resolved current 
working directory.

Additionally, source filenames in debug info are relative to (it seems)
the current working directory.

Meanwhile I tested the IDE, and indeed the paths are passed using full paths.
I am glad this is so, and wonder how long I've been in the dark erroneously :(

In that case, may I suggest to leave the 'Show relative paths' unchecked 
by default in the "show options" dialog (or save its state)? 
It will then by default match the parameters as they are actually passed to the compiler.

It seems then that the relative filenames in the debug info are the cause of the IDE 
opening the same file twice when using symlinks.

Since this is a major annoyance I think this behaviour should become configurable in FPC.
