Hard to tell. The default compiler usually comes from some binary package of 
the distribution, and that usually includes lots of patches to the upstream 
sources.

Not necessarily for include headers from other packages, and especially not 
when you try to compile a newer version of GCC. With new standards, GCC might 
consider certain constructs to be invalid that where accepted before.
