That sounds more like a FPC bug than Lazarus. Lazarus only checks file
dates. If a change is in interface or implementation doesn't matter.
Or maybe I misunderstand?

I'm not sure what you mean 'build Lazarus itself' and 'Lazarus is owned
by the "root"'.
Can you give more details?

Do you mean lazbuild -B or fpc -B?

-s Silent operation; do not print the commands as they are executed.

'make clean' in Lazarus source directory deletes .ppu and .o files of
IDE, lazbuild and bigide components. This is useful, when a source file
was removed from a package.
