--- Comment #10 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Still  fails on the trunk:
apinski@xeond:~/src/upstream-gcc$ echo "int main(void){}" |
~/upstream-gcc/bin/gcc -xc  -save-temps - -c
cc1: error: unrecognized command-line option ‘-.i’


Note without the -c, it works as the output is based on a.out so it is a--.i
now.
