[Dune] [Dune-Commit] dune-common r6505 - trunk/m4

[Christian Engwer]

Hi Oli,

do all compiler, which support __attribute__((deprecated)) also
__attribute__((deprecated))(msg) ?

I'm not sure!

I this case you will have to check for both feature independently and
also provide a fallback
DUNE_DEPRECATED_MSG="__attribute__((deprecated))"
in case the message does not work.
