Gcc 4.0.2 RC1 checking not disabled?

[Gcc K6 testing account]

Ave gcc people


Build environment: 
-Redhat 7.3 with fedora legacy updates.
-gcc build configured with : ../configure --prefix=/opt/gcc-4.0.2-RC1
--enable-languages=c,c++ --enable-threads=posix --disable-shared


My build of gcc 4.0.2 RC1 is still bootstrapping but I see these snippets 
in my log.

<knipperdeknip>
make CC="gcc" libdir=/opt/gcc-4.0.2-RC1/lib LANGUAGES="c " \
        CFLAGS="-g -DENABLE_CHECKING -DENABLE_ASSERT_CHECKING" \
        MAKEINFO="/tmp/workdir/gcc-4.0.2-20050913/missing makeinfo 
--split-size
        COVERAGE_FLAGS= OBJS-onestep="tree-chrec.o tree-scalar-evolution.o 
tree
make[2]: Entering directory `/tmp/workdir/gcc-4.0.2-20050913/objdir/gcc'
</knipperdeknip>



Is "-DENABLE_CHECKING" supposed to happen in a RC/release?
Or has -DENABLE_CHECKING nothing to do with the configure 
option --enable-checking?
