For GNAT, yes.

Simple solution: if you have x.adb containing procedure Main and procedure Sub,
run "gnatchop x.adb" which will split the procedures into separate files called
main.adb and sub.adb, then run "gnatmake main.adb" which will compile Main and
any other units that it depends on (in this case, Sub). Note that Main will
need to say "with Sub;" at the top...
