[Bug driver/28528] New: [4.0/4.1/4.2 regression] Trouble compiling header files with "-x c++" using g++

[reichelt at gcc dot gnu dot org]

The g++ driver has problems with *.h files compiled with "-x c++":
  g++ -c -x c++ file.h
yields a precompiled header file.h.gch instead of file.o.
  g++ -S -x c++ file.h
yields an error message:
  cc1plus: error: output filename specified twice

With "-x c" everything works as expected. Also using gcc (and not g++)
with "-x c", "-x c++", "-x c-header", "-x c++-header" works fine.

This is a reression from GCC 3.3.x where using
  g++ -c -x c++ file.h
or
  g++ -S -x c++ file.h
led to the desired results.
