Hi,

In the source package. Debian has all build stuff in the source tree
in sub directory debian/.

To get the source tree just say the following on a debian system:

    $> mkdir gnat         # apt-get fetches multiple files, this dir to keep all together
    $> cd gnat

    $> apt-get source gnat

    (... lots of stuff happen here: archive is fetched and unpacked )


    $> cd gnat-3.15p/debian/

    $> ls
   
    changelog  README.Debian rules control

    (...)


The build rules are in the file 'rules'. This is actually a makefile
and the target from which all build actions flow is (surprisingly)
called 'build'.

build: build-stamp
build-stamp: patch-stamp config-stamp compiler-stamp static-stamp \
        shared-stamp tools-stamp
        dh_testdir
        touch build-stamp


compiler-stamp: config-stamp
        $(MAKE) CFLAGS='-O2' GNATLIBCFLAGS="$(GNATLIBCFLAGS)" LANGUAGES='c ada'
        touch compiler-stamp


config-stamp:
        CC=gnatgcc ./configure --prefix=/usr --host=$(OS) --target=$(OS)
        cd ada && touch treeprs.ads a-einfo.h a-sinfo.h nmake.adb nmake.ads
        # Prevent running autoheader, which isn't necessary
        touch cstamp-h.in
        touch config-stamp

(...)


and so on. i think xou get picture. Much luck :-).
