* flags.h (warn_padded, warn_packed): Add global var decls. * toplev.c (warn_padded, warn_packed): Add global var defns. (W_options): Add warnings `-Wpacked' and `-Wpadded'. * stor-layout.c (layout_record): Add local variable `type' to hold often-used TREE_TYPE (field). Add local variable `unpacked_align' to hold alignment that would be in force if no `packed' attribute were present. Warn if `packed' attribute is unnecessary, or even harmful. Warn when gcc inserts padding to satisfy alignment requirements of members. Use NULL_TREE when checking whether var_size is set. * invoke.texi: Document new flags.
