Understood, but it already was UB in 1996. Past mistakes do not excuse 
insisting on it.

The issue might be less with the WG14-defined symbols, but with GCC's own, 
because those would also start with "G". In this case, it also starts with the 
letter "G", but as Bartosz says, he's only following existing practice. So it 
stands to reason that other projects whose names do not start with "G" may do 
the same and run into problems later.

Glib should not advise people to write UB code.

Anyway, advice given.
