Bug#114216: gcc: exits successfully if there's no compiler for a language

[Zack Weinberg <zack@codesourcery.com>]

Package: gcc
Version: 2:2.95.4-6
Severity: normal

When one invokes the compiler driver on a language (e.g. Ada) for which
there is no front end installed, it exits successfully, which causes Make
to think that the compilation succeeded.  Observe:

$ touch ada.ads
$ gcc -c -v ada.ads ; echo $?
Reading specs from /usr/lib/gcc-lib/i386-linux/2.95.4/specs
gcc version 2.95.4 20010902 (Debian prerelease)
gcc: ada.ads: Ada compiler not installed on this system

This bug is present in gcc 3.0 as well.
