Compiling Gnat 3.13 on Solaris 8

[Giovanni . La . Rocca]

Hello,

I need to compile the GNAT ver. 3.13 on Solaris 8.
I have compiled and installed gcc 3.0 and now I want to compile ada too.
To do this I need gcc (OK) and
a previous working version of ada,

I've been searching for a while for the sources of a previous Gnat
version but with no success.
Also, I did not succeed in finding al least a binary distribution for
Solaris 8 (to use as a 'bootstrap').

Any ideas of where I can find any of the above ?

Thanks in advance
Giovanni
