@section Building the Ada compiler
In order to build GNAT, the Ada compiler, you need a working GNAT
compiler, since the Ada front end is written in Ada (with some
compiler (GNAT version 3.13 or later, or GCC version 3.1 or later),
since the Ada front end is written in Ada (with some
GNAT-specific extensions), and GNU make.
However, you do not need a full installation of GNAT, just the GNAT

C compiler (the compiler driver can be different or not).
@command{configure} does not test whether the GNAT installation works
and has a sufficiently recent version; if too old a GNAT version is
installed, the build will fail unless @option{--enable-languages} is
used to disable building the Ada front end.
Additional build tools (such as @command{gnatmake}) or a working GNAT
run-time library installation are usually @emph{not} required. However,
