+2012-07-17  Eli Zaretskii  <eliz@gnu.org>
+
+        Remove FILE_SYSTEM_CASE.
+        * s/msdos.h (FILE_SYSTEM_CASE): Don't define.
+
+        * fileio.c (FILE_SYSTEM_CASE): Don't define.
+        (Ffile_name_directory, Fexpand_file_name): Don't use FILE_SYSTEM_CASE.
+        Fixes problems on MS-DOS with Vtemp_file_name_pattern when
+        call-process-region passes it through expand-file-name.
+
+        * dired.c (file_name_completion): Don't use FILE_SYSTEM_CASE.
+
+2012-07-17  Andreas Schwab  <schwab@linux-m68k.org>
+
+        Fix crash when creating indirect buffer (Bug#11917)
+        * buffer.c (buffer_lisp_local_variables): Add argument CLONE.
+        Don't handle unbound variables specially if non-zero.
+        (Fbuffer_local_variables): Pass zero.
+        (clone_per_buffer_values): Pass non-zero.
+
+2012-07-17  Andreas Schwab  <schwab@linux-m68k.org>
+
+        * gnutls.c (emacs_gnutls_handshake): Revert last change.  Add QUIT
+        to make the loop interruptible.
+
