[Ada] Bootstrapping mainline GNAT fails

[Richard Kenner]

    I am using GNAT 3.14p to compile Ada sources, and GCC 2.95 to compile
    C sources; the resulting object modules are then linked together to
    make stage1/gnat1.  Is that what you mean by a kludged-up compiler?

No, I mean a gnat1 built using GCC 2.95 or 3.0 sources.  It indeed
does not matter what is used to compile the C parts.
