* configure.ac (enable-checking): Explicitly set all variables for
	collective switch values.  Alphabetize variables. Rename
	ac_checking_valgrind to ac_valgrind_checking.  Allow 'none' as
	synonym for 'no'.

When you specify this option, the compiler is built to perform checking
of tree node types when referencing fields of that node, and some other
internal consistency checks. This does not change the generated code,
but adds error checking within the compiler. This will slow down the
compiler and may only work properly if you are building the compiler
with GCC@. This is on by default when building from CVS or snapshots,
but off for releases. More control over the checks may be had by
specifying @var{list}; the categories of checks available are
@samp{release}, @samp{assert}, @samp{misc}, @samp{tree}, @samp{gc},
@samp{rtl}, @samp{rtlflag}, @samp{runtime}, @samp{fold}, @samp{gcac} and
@samp{valgrind}. The @samp{release} category enables only those checks
suitable for release builds, currently this is @samp{assert} and
@samp{runtime}. The check @samp{valgrind} requires the external
@command{valgrind} simulator, available from
@uref{http://valgrind.kde.org/}. The checks @samp{rtl}, @samp{gcac} and
@samp{valgrind} are very expensive. The default when @var{list} is not
specified is @samp{assert,misc,tree,gc,rtlflag,runtime}. That is also
the default for development builds, when @samp{--enable-checking} is not
specified. For release builds the default, when
@samp{--enable-checking} is not given, is @samp{release}. To disable
all checking, @samp{--disable-checking} must be explicitly requested.
Disabling assertions will make the compiler and runtime slightly faster
but increase the risk of undetected internal errors causing wrong code
to be generated.
When you specify this option, the compiler is built to perform internal
constency checks of the requested complexity. This does not change the
generated code, but adds error checking within the compiler. This will

from CVS or snapshots, but @samp{release} for releases. More control
over the checks may be had by specifying @var{list}. The categories of
checks available are @samp{yes} (most common checks
@samp{assert,misc,tree,gc,rtlflag,runtime}), @samp{no} (no checks at
all), @samp{all} (all but @samp{valgrind}), @samp{release} (cheapest
checks @samp{assert,runtime}) or @samp{none} (same as @samp{no}).
Individual checks can be enabled with these flags @samp{assert},
@samp{fold}, @samp{gc}, @samp{gcac} @samp{misc}, @samp{rtl},
@samp{rtlflag}, @samp{runtime}, @samp{tree}, and @samp{valgrind}.
