configuration in gcc build

["Dima Sorkin" <dima.sorkin@xxxxxxxxx>]

Hi.
release gcc 4.1.2

Ocassionally I found out that by default Ada will not be built,
contrary to written in the install docs:
http://gcc.gnu.org/install/configure.html

In the file "gcc-4.1.2/gcc/ada/config-lang.in" of Ada component,
on last line, the following appears:
-----------------
# Ada will not work until the front end starts emitting GIMPLE trees.
build_by_default=no
----------------

Is it a documentation bug ?

Thanks,
Dima.
