+
+ * data-in.c: Make formatted data parsing locale-independent.
+ (parse_number): Use c_strtod instead of strtod, to avoid
+ locale-specific behavior.
+ (parse_Z): Ditto.
+
+2007-11-06 Ben Pfaff <blp@gnu.org>
+
+ Patch #6256: add support for binary, 360 file formats. Reviewed
+ by John Darrington.
+
+ * data-in.c (struct data_in): Add `encoding' member.
+ (data_in): Add `encoding' parameter, and re-encode the data passed
+ in where appropriate. Update all callers to pass it in.
+ (parse_A): Implement EBCDIC recoding wart described in manual.
+ (parse_AHEX): Implement EBCDIC recoding.
+
+ * data-out.c (data_out_legacy): New function.

+
+ Patch #6258. Reviewed by John Darrington.
+
+ * file-handle-def.c (fh_lock): Add comment that TYPE should be
+ marked with N_() in the caller. Added these markings to each
+ caller too. Should make i18n easier.
+ Suggested by Chusslove Illich <caslav.ilic@gmx.net>.

+
+ Allow output files to overwrite input files (bug #21280).
+
+ * file-handle-def.c: Separate locking of files for input and for
+ output, to allow both to take place at once. Also, distinguish a
+ file handle from the identity of the underlying file, because the
+ identity of a file changes over time and the file handle can't
+ represent two different identities.
+ (struct file_handle): Remove `next', `open_cnt', `deleted',
+ `type', `open_mode', `aux', `identity' members. Change `id' from
+ char array to char *. Add `ref_cnt' member.

+ environments.
+ (struct file_identity): New `name' member.
+ (fn_get_identity): For a file that doesn't exist, get the
+ dev/inode of its directory plus its name. If even the directory
+ doesn't exist, just use its name. Merge the Windows
+ implementation into the Unix one.

+ a scratch file.
+
+ * scratch-writer.c (struct scratch_writer): Add `lock' and `dict',
+ remove scratch_handle member.
+ (scratch_writer_open): Lock handle. Prepare to replace handle

+2007-11-02 Ben Pfaff <blp@gnu.org>
+
+ * data-out.c (output_number): Use isfinite (from C99) instead of
+ gsl_isfinite, since we now have universal support for it in
+ gnulib.
+ (output_infinite): Ditto.
+ [!HAVE_ROUND] (round): Remove definition, since we now have a
+ replacement in gnulib.

+
+ * file-name.c (create_stream): New function.
+
+ * por-file-writer.c (pfm_open_writer): Use fh_open to open the

+
+ * settings.c settings.h: Changed viewport's length and width to be
+ owned by the user interface which uses the data library. This allows
