[Bug driver/17361] New: gcc driver complains about C++ options when assembling

[markus at oberhumer dot com]

gcc has always ignored C/C++ options when assembling, but apparently some new
checks for explicit C++ options do not follow this principle.

Confirmed.
The problem is that cpp0 is no longer the preprocessor and that cc1 is the preprocessor for ASM.  
Maybe we should turn off the warning if -lang-asm is passed to cc1.

This seems to be fixed for 3.4 and 4.0 now, so the bug should be closed.
