g++ -v fails

[KO Myung-Hun]

Hi/2.

g++ -v requires a input file and return an error status. Due to this, configure test for this fails, and libtool cannot generate DLLs for C++. However gcc -v works as expected.

gcc -v :

patch for g++ -v

This occurs if GCCOPT is set. For examples, GCCOPT=-pipe.

I tested this with gcc 4.9.2 and there it works. Does it really make sense to work on this old compiler at all? I personally doubt.
