FLEXARRAYMEM

Message        <Context> allowing the struct member, "<name>" to be
               a struct with a flexible array member is a language
               extension.

Description    The C99 standard allows the final element of a struct
               with more than one named member to have incomplete
               array type.  Such a member is called a flexible array
               member.  The standard does not allow such a struct
               (and any union containing, possibly recursively, a
               member that is such a struct) to be a member of
               another structure.  Other C compilers may not support
               this extension.

User Action    Be aware of this extension if you wish to port the
               code.
