[Lazarus] need info some warning

[FreeMan]

Been long time I saw this warnings when compile project and while svn 
updateing too.

project1.lpr(21,1) Warning: "crti.o" not found, this will probably cause 
a linking failure
project1.lpr(21,1) Warning: "crtn.o" not found, this will probably cause 
a linking failure

In project1.lpr file line 21 is "end."

This report on svn updateing too.
/usr/bin/ld: warning: /opt/lazarus/link.res contains output sections; 
did you forget -T?
what I forget ?

Has any one info about thats? Thats just warning, but why?
