There's something else on the same topic:

http://gcc.gnu.org/onlinedocs/gcc-4.1.2/gnat_ugn_unw/Switches-and-Project-Files.html
(documentation says)

So there is finally an exception with the `--RTS` option. But that  
document talks about GNATMake, not GPRBuild. Also, it says nothing about  
the same option in a project file.

(still searching for more material)
