+       Make casewriters keep track of the number of `union value's in
+       each case.  This is useful for two reasons: casewriter_write can
+       then check that the case being written is large enough, and later
+       recipients of the casewriter can determine the size of the case.
+       
+       * casewriter-translator.c (casewriter_create_translator): Add
+       value_cnt parameter.
+       
+       * casewriter.c (struct casewriter): Add value_cnt member.
+       (casewriter_write): Check that the case passed in is big enough.
+       (casewriter_get_value_cnt): New function.
+       (casewriter_create): Add value_cnt parameter.
+

+       Fix bug reported by Jason Stover.
+       * settings.c: Move get_termcap_viewport and in particular the
+       #include for <curses.h> to the end of the file.  curses.h
+       redefines bool on some systems (e.g. OpenBSD), which causes
+       disagreement between uses of bool before its inclusion and
+       afterward.
+       Tested by Jason Stover.

+
+       Provisional fix for bug #18692 and bug #20161.  Reviewed by John
+       Darrington.
+
+       * file-name.c (fn_open): Only pass "r" or "w" to popen as mode
+       argument (never "rb" or "wb") because SUSv3 says that only those
+       modes are defined, and glibc in fact rejects other modes.
+
+       Open portable files with fn_open so that they can be read from
+       pipes.  Fix missing fh_close call to go along with fh_open.
+       Report an error if the file close reports an error.
+       * por-file-reader.c (close_reader): New function.
+       (por_file_casereader_destroy): Use close_reader.
+       (pfm_open_reader): Open file with fn_open.

+
+       Make PSPP able to read all the portable files I could find on the
+       web.  Thanks to John Darrington for review.  Bug #17620.
+       * por-file-reader.c (struct pfm_reader): New member `line_length'.
+       (error): Print file offset in hexadecimal.
+       (warning): New function.
+       (advance): Treat lines less than 80 bytes long as padded to 80
+       bytes with spaces.
+       (pfm_open_reader): Call read_documents if we find an "E" record.
+       (convert_format): Convert invalid formats to the default format
+       instead of aborting reading the file.
+       (read_variables): Rename duplicate variable names instead of
+       aborting reading the file.
+       (read_value_label): Allow string variables of different widths to
+       be assigned value labels in the same record.  Replace duplicate
+       value labels instead of aborting.
+       (read_documents): New function.
+
+       * por-file-writer.c (pfm_open_writer): Call write_documents if the
+       dictionary has documents.
+       (write_documents): New function.
