[Bug c++/14432] New: [3.4/3.5 regression] Built-ins lead to conflict even if no header file included

[bangerth at dealii dot org]

[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.

Confirmed, in fact it is an extended builtin. And also the C front-end just warns about this instead of 
erroring out.
