>=gcc-4.5.0 failing to compile with --disable-checking

["Raúl Porcel" <armin76@gentoo.org>]

Hi Uros,

Using latest trunk, with:
../configure --host=alpha-unknown-linux-gnu
--build=alpha-unknown-linux-gnu --enable-languages=c --disable-checking

and

make -j5 bootstrap-lean

Fails with the following error:

make[3]: Entering directory `/root/gcc/trunk/build'
rm -f stage_current
make[3]: Leaving directory `/root/gcc/trunk/build'
Comparing stages 2 and 3
