Maybe you should start to do that though. Otherwise you'll simply lose
the easy (but not required) testing of Ada when I (or others) backport
changes to still maintained branches on machines where the system Ada
compiler is newer than the oldest maintained branch.
So - it's all for your own benefit ;) [you can think of using a new
-we-are-building-gcc
switch for the compile where you'd enable some backward compatibility or so]
Thanks,
Richard.
