Remaining problems:
1) the default GNU/Hurd gcc complier deriver does not recognize ada
libraries: fixes by enable_ada_for_hurd.diff
2) built binaries segfaults at startup (dynamic and static: sjlj and
zcx): remains to solve

Download and install the built gnat debs:
=========================================

apt-get install gnat

Download the patches
====================
darnassus.sceen.net:~gnu_srs/gnat-4.6/patches/*.diff

Debian specific patches:
enable_ada_for_hurd.diff
debian_rules.patch.diff
ada-bug564232_new.diff
ada-libgnatprj_new.diff

Upstream patches: 
(Debian for now, for upstream when the segfault problems are solved)
gcc_ada_gcc-interface_Makefile.in.diff
s-osinte-gnu.diff: FIXME
s-taprop-gnu.diff: FIXME

Install the gnat-4.6 and gcc-4.6 sources:
=========================================
cd .../gnat-4.6
apt-get source gnat-4.6 (4.6_4.6.3-2)
unpacks to gnat-4.6-4.6.3
debian/ _MIN/

As root: apt-get source gcc-4.6 (4.6_4.6.3-1+hurd.1)

Installs gcc-4.6 at /usr/share and
/usr/src/gcc-4.6
debian  gcc-4.6.3-dfsg.tar.xz  patches

pwd
/home/srs/DEBs/gnat/gnat-4.6.3/gnat-4.6-4.6.3
ln -s /usr/src/gcc-4.6/gcc-4.6.3-dfsg.tar.xz .

Unpacking the gcc-4.6 sources
=============================
debian/rules unpack 2>&1 | tee ../unpack_gnat-4.6.3.log
creates stamps/
01-unpack-stamp  01-unpack-stamp-gcc-4.6.3-dfsg.tar.xz

Enabling and applying the Hurd-specific patches:
================================================
Add the patches to debian/patches

Mmodify debian/patches/series:
ada-link-lib.diff -p1
ada-libgnatvsn.diff -p1
-ada-libgnatprj.diff -p1
+ada-libgnatprj_new.diff -p1

Note: Make sure that the hurd-fixes.diff is applied (not in series file)
+hurd-fixes.diff -p1


Make sure every patch changing a configure.ac creates a new configure:
(cd src; autoconf2.64): ada-link-lib.diff
(cd src/libgnatprj; autoconf2.64): ada-libgnatvsn.diff
(This is done later at the patch stage, but just to be sure!)

Patching
========

Configuring
===========
debian/rules configure 2>&1 | tee ../configure_gnat-4.6.3.log

Creates build/
Makefile, config.* etc!

Building
========
debian/rules build 2>&1 | tee ../build_gnat-4.6.3.log

Creating debs
=============
debian/rules binary 2>&1 | tee -a ../binary_gnat-4.6.3.log

Of course the build can be made in one stage (if all the above steps
succeeds)

dpkg-buildpackage -b (or whatever)
