[Bug fortran/20780] New: gcc 4.0 from cvs head fails to build

["federico dot carminati at cern dot ch" <gcc-bugzilla at gcc dot gnu dot org>]

I start the build with

export CVS_RSH=ssh
cvs -qz9 up -Pd gcc
rm -rf /opt/gcc-4_0/*
[ -d build ] && (rm -rf build ; mkdir build)
cd build
../configure --disable-multiplib --prefix=/opt/gcc-4_0 --with-gmp=/sw --enable-
languages=f95,c++
make 2>&1 | tee ../make.log
make install
 
Build dies with

gcc   -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes  -fno-
common   -DHAVE_CONFIG_H    -I. -I. -I../../gcc -I../../gcc/. -I../../gcc/../include -I./../intl -I../..
