Synopsis: -std=gnu99 and casted empty srtuct initializers
State-Changed-From-To: open->closed

State-Changed-Why:
This is deliberate. C99 compound literals are not
constant expressions but unnamed variables intitialized
in a given way. The code you give is equivalent to
foo_t compound_literal = { };
foo_t baz = compound_literal;
which of course fails. As an allowance for existing
code written for old GNU compound literals rather than
C99 compound literals (the Linux kernel), this case
is permitted in gnu89 mode but not gnu99 mode.
