Somebody suggested the GNAT is going to skip one gcc release. And I frear
3.4 is just that version. While the 3.5 brach version at least compiles ok
the 3.4 bracne has not produced gnat executables for the last 2 weeks.

That is also the reason why there is no 3.4 release of ASIS.

I do updates on both on a regular basis. Once you have the source the update
does not take that long.
