I use the same versions and are relatively happy.

Not perfectly. It gets confused after a use statement inside a package body.
E.g.
	package body blabla is
	   package int_io is new integer_io (integer);
	   use int_io;

now the indentation is completely different from what it would be
without the use clause.

I suspect you are on the wrong trail here. It would be better if you
could rely on make to know how to make an executable from Ada sources.
Unfortunately you can't yet.

If you have a C-source xyz.c and want to have the executable xyz then
you can simply say make xyz. That's why emacs suggests the "make -k"
command line.

I use the following Makefile to achieve a similar effect with ada
sources too. It declares a few new "pattern rules" (works only with
GNU-make).

=======================================================================
#
# Makefile --- Makefile for GNU-make, make executables from Ada sources
#

# for OS/2 use:
O       = .obj
E       = .exe

# for Unices use:
ifdef HOSTNAME # a variable only defined in unix
O       = .o
E       = 
endif

CC      = gcc
ADAC    = $(CC)
GF      = -O2 -fomit-frame-pointer
BF      = -s

%.ali %$O : %.ads %.adb
		$(ADAC) -c $(GF) $*.adb

%.ali %$O : %.adb
		$(ADAC) -c $(GF) $<

%.s : %.adb
		$(ADAC) -S $(GF) $< -o $@

%$O : %.c
		$(CC) -c $(CFLAGS) $< -o $@

%.s : %.c
		$(CC) -S $(CFLAGS) $< -o $@

%$E : %.ali %$O
		gnatbl $(BF) $< -o $@
=======================================================================
(Don't cut/paste this text from an xterm, the tabs are important!)

Note that this Makefile doesn't contain any target. You can include it
in your Makefiles and add targets or simply say "make target" when
there is a target.adb source.

There are a few rules to build executables from multiple sources. The
dependency is chained using the *.ali files GNAT produces along with
the objects.

What more good ideas on using make with GNAT do you have?
