Don't you need to add the c part of it ? (gnat 3.10p)
a-adaint.c a-raise.c a-argv.c a-sysdep.c
a-cio.c a-time.c a-cstrea.c a-trans.c
a-deftar.c a-trans3.c a-errno.c a-trans4.c
a-exit.c a-uintp.c ...

For example :

__gnat_raise_constraint_error is in a-raise.c
gnat_argc is in a-argv.c

Hope it will help...
