Ah, yes, I would like to conclude that your 'gcc' is not what I would
expect it to be. Care to do gcc -v?

And your g++ seems to do it.

You don't need to, you can set the compilers in the configuration menu.
I cannot say if anything works at all if you change the compilers this
way. Better find out what gcc is doing.
