[Bug c++/15862] New: 'enum yn' fails

[pepster at users dot sourceforge dot net]

This short code snippet fails to compile. Worked in 3.3.
As far as I can tell, yn is not a reserved word.

enum yn {Y, N};
enum yn x = Y;

Confirmed, a regression.

Mark I feel that this is major parser bug which should be fixed for 3.4.1.

No, yn is one of the Bessel function functions in C99 (do 'man yn'). 
The is a duplicate of another bug involving j1, which I'm going to look 
up next.

That would be PR 14432 but since my 3.5.0 build was from last night this is not fixed.

Right, I found PR 14432 as well. However, my 3.4 build compiles that one 
correctly, while it still fails on this PR. Mark, do you have an idea what 
is going on? This just seems too close to 14432 to be a coincidence...
