[Extracted from 14430] Consider this:
--------------
struct Y {};
Y y1;
--------------
There are no header files included, yet we get from mainline and 3.4:
g/x> /home/bangerth/bin/gcc-3.5-pre/bin/c++ -c x.cc
x.cc:2: error: declaration of `Y y1'
<internal>:0: error: conflicts with previous declaration `double y1(double)'
This is due to the fact that there is a built-in for the Bessel function y1.
However, it should certainly not be visible if no header files are included.
That's the bug, and it is a regression against 3.3.x.
