It looks like cc1 treats
/usr/lib64/gcc/x86_64-suse-linux/4.6/cc1 -quiet -v "" t.c -quiet -dumpbase t.c
-mtune=generic -march=x86-64 -auxbase t -version -o /tmp/ccYYppXF.s
as reading from stdin? Yes, it does,
gcc -Wp, -c t.c < /dev/null
works just fine.
Somewhat odd behavior though ;) Confirmed. The driver should either
drop empty -Wp, or error.
