Then perhaps we just need an improved autoconf/configure test, so
that we don't *by default* attempt to build the ada front-end when
we know in advance that this will fail. A fatal error in the bootstrap
process not only affects Ada, but the entire GCC distribution.
Requiring the user to diagnose the problem, and therefore configure
GCC with --enable-languages="c,c++,objc,f77,java" on future Linux
distributions, would be a regression from gcc 3.0.4 atleast.
Unfortunately, configury is a black-art to me, or I'd propose a
patch myself.
