I suspect I can't build gnat in gcc-3.3.5 using gcc-3.4.2 then... or?

Well it is very unusual to have a private copy of system.ads, but
if you do, it makes sense for the compiler to use it.

I've run into this problem too.  Here is a vague recollection:

When gnat starts up, it looks for a system.ads file and reads it in.
Unfortunately, the search strategy for "system.ads" looks in the
program-being-compiled first, so your gnat 3.4.2 is picking up
"system.ads" from whatever program you are compiling.

I can't see why this would ever be correct -- I think gnat should
always use its own "system.ads" file from the gnat installation
directory.

Anyways, that's a vague explanation and it might have errors.
Perhaps a more fluent Ada guy can give a more accurate explanation.
