Subject: [PATCH] include/c.h: handle members of const struct
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Trying to copy into a local const struct will lead to a compiler error.
By adding a "+ 0" to the argument of __typeof__() the type of the
resulting express will loose its constness.
