    Port to stricter C99 platforms. · 91f2d272

    Especially, C99 prohibits nesting a struct X inside struct Y if
    struct X has a flexible array member.
    Also, merge from gnulib, incorporating:
    2013-11-03 intprops: port to Oracle Studio c99
    * lib/intprops.h: Update from gnulib.
    * src/alloc.c (struct sdata): New type.
    (sdata): Implement in terms of struct sdata.
    Remove u member; all uses replaced by next_vector, set_next_vector.
    (SDATA_SELECTOR, SDATA_DATA, SDATA_DATA_OFFSET): Adjust to sdata change.
    (SDATA_DATA_OFFSET): Now a constant, not a macro.
    (struct sblock): Rename first_data member to data, which is now
    a flexible array member.  All uses changed.
    (next_vector, set_next_vector, large_vector_vec): New functions.
    (vector_alignment): New constant.
    (roundup_size): Make it a multiple of ALIGNOF_STRUCT_LISP_VECTOR, too.
    (struct large-vector): Now merely a NEXT member, since the old approach
    ran afoul of stricter C99.  All uses changed to use
    large_vector_vec or large_vector_offset.
    (large_vector_offset): New constant.
    * src/dispnew.c: Include tparam.h, for tgetent.
    Do not include term.h; no longer needed.
    * src/gnutls.c (Fgnutls_boot): Don't continue after calling a _Noreturn.
    * src/lisp.h (ENUM_BF) [__SUNPRO_C && __STDC__]: Use unsigned int.
    (struct Lisp_Vector): Use a flexible array member for contents,
    instead of a union with a member that is an array of size 1.
    All uses changed.
    (ALIGNOF_STRUCT_LISP_VECTOR): New constant, to make up for the
    fact that the struct no longer contains a union.
    (struct Lisp_Misc_Any, struct Lisp_Marker, struct Lisp_Overlay)
    (struct Lisp_Save_Value, struct Lisp_Free):
    Use unsigned, not int, for spacers, to avoid c99 warning.
    (union specbinding): Use unsigned, not bool, for bitfield, as
    bool is not portable to pre-C99 hosts.
