Binaries from gnat-3.10p.....tar.gz are built using gcc-2.7.2.1 and libc.so.5
This installation overwrite /usr/bin/gcc and does not work.

I have found a dirty trick :  use the package gnat-3.10 from debian/hamm/devel
This package is compiled with glibc2.0, gcc-2.7.2.3 and does not divert gcc.

1. get the package debian/hamm/binary-i386/devel/gnat_3.10p-2.deb
2. get the debian binary dpkg-deb or compile it from  source :
      debian/bo/source/base/dpkg_1.4.0.8.tar.gz 
		2.1 cd /tmp ; tar xvfz dpkg_1.4.0.8.tar.gz
		2.2 cd dpkg-1.4.0.8 ; ./configure
		2.3 cd lib ; make
		2.4 cd ../dpkg-deb ; make
		2.5 Use dpkg-deb in step 4
3. Using my redhat-5.0, gcc-lib is  /usr/lib/gcc-lib/i386-redhat-linux/2.7.2.3
control this path with gcc -v
then link 
ln -s /usr/lib/gcc-lib/i386-redhat-linux  /usr/lib/gcc-lib/i486-linux

4. logged as root :
dpkg-deb -x gnat_3.10p-2.deb   /

which extracts  binaries  from gnat_3.10p-2.deb in /   (dpkg-deb --help)

5. ldconfig
