       that the result is also a unibyte string.

       create unibyte strings from default paths and directory/file

       directory/file names.
       src/buffer.c (init_buffer): Don't store default-directory of

       that is described in

      Port to stricter C99 platforms. · 91f2d272
      Paul Eggert authored
      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.
