    Add support for compound literal in expr.c
    
    The support is not yet complete because initilist() is wrong.
    We do not support designator lists, and we fail to decide
    when an initializator is missing the braces. At this point
    it works for C90 initializers, but it fails when there is
    some compound literal.
