[PATCH 0/4] {master} introduce and use -Wdeprecated

[Akim Demaille]

Recent history shows that there are many features in Bison
that occasionally need to be upgraded.  Having a means to
report deprecated features will certainly help.

I hesitated on the name, as for instance Automake uses -Wobsolete.
But GCC seems to prefer "deprecated" to "obsolete", so I preferred
that path.  We can always add -Wobsolete as an alias for -Wdeprecated.

Not pushed, waiting for comments.

Akim Demaille (4):
  undefined but unused is a warning
  introduce -Wdeprecated
  use -Wdeprecated for obsolete %define variable names
