On a related note I'm unable to build Ada on the 3.2 branch using
a version of Ada built from the 3.3 branch. The problem is 3.3
doesn't like the 3.2 system.ads file.
Yes, that is expected. The issue is that the system.ads file is read by
the compiler at run time to determine a number of parameters in use for
the target, such as choice of exception handling model. When a new
version of the compiler adds more parameters, the old system.ads version
is no longer sufficient. In general, you should build version X of the
front end with version X or X-1.
