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

I think that is the main reason, but that was for the IDE/designers benefit,
not the compiler's. Just like the form names are mentioned in comments in
the .dpr. 

Later the syntax was recycled to tackle file case problems on Kylix.

But the problem is what are relative paths relative too? Project file? The
actual source file?

IMHO these are all shaky uses cases, and actually doing it right is quite
hard.
