Here are the steps I use to build a gnat cross:

    cd ~/ST5/Tools
    mkdir build-mips-rtems-ada
    cd build-mips-rtems-ada
    ../gcc-2.8.1/configure --prefix=/home/stephe/ST5/Ada_Install --target=mips-rtems --with-gnu-as --with-gnu-ld --enable-languages=c,ada

    ~/ST5/Tools/build-mips-rtems-ada/Makefile :
        make CFLAGS="-O2 -g" all
            # CFLAGS drops -Wall from default; lots of bogus warnings in Ada compiler

        make CFLAGS="-O2" GNATLIBCFLAGS="-O2 -I/home/stephe/ST5/C_Tools/mips-rtems/include" gnatlib
            # extra -I is for sys/types.h etc
        make CFLAGS="-O2" cross-gnattools
        make CFLAGS="-O2" ada.all.cross

        make install

This list was derived partly from help from ACT, partly from black
magic. You are entitled to wear a wizard's cap after you get this
working :).

I'm not sure there's much difference. Assuming you use Ada.Text_IO in
helloworld, that's pretty much the whole compiler and run-time
library; it doesn't come in smaller pieces.
