+
+	New module 'count-trailing-zeros'.
+	* MODULES.html.sh: Mention it.
+	* lib/count-trailing-zeros.c, lib/count-trailing-zeros.h:
+	* m4/count-trailing-zeros.m4, modules/count-trailing-zeros:
+	* modules/count-trailing-zeros-tests:
+	* tests/test-count-trailing-zeros.c:
+	New files.
+
+	count-leading-zeros: port to MSC; support types wider than 64 bits
+	The ideas behind the MSC port are stolen from Emacs.
+	* lib/count-leading-zeros.h:
+	Don't include verify.h: it's no longer needed, as types wider than
+	64 bits are now supported.
+	(COUNT_LEADING_ZEROS): New arg MSC_BUILTIN, for better
+	performance with MSC.  All uses changed.  Do not assume that TYPE
+	has at most 64 bits.
+	(count_leading_zeros_32): Assume 0 < X < 2**32, for speed.
+	All uses changed.  Fold the subtraction from 31 into the table.
+
+	count-one-bits: port to MSC; support types wider than 64 bits
+	The ideas behind the MSC port are stolen from Emacs.
+	* lib/count-one-bits.c (popcount_support) [_MSC_VER]: New variable.
+	* lib/count-one-bits.h: Include limits.h, for CHAR_BIT.
+	Don't include verify.h: it's no longer needed, as types wider than
+	64 bits are now supported.
+	(COUNT_ONE_BITS_GENERIC): New macro.
+	(popcount_supported) [_MSC_VER]: New inline function.
+	(COUNT_ONE_BITS): Use it.  New arg MSC_BUILTIN, for better
+	performance with MSC.  All uses changed.  Do not assume that TYPE
+	has at most 64 bits.
+	* modules/count-one-bits (Depends-on): Do not depend on 'verify'.

+
+	mountlist: fix resource leak with MOUNTED_INTERIX_STATVFS
+	* lib/mountlist.c (read_file_system_list): fix leak of directory
+	streams in case of #ifdef MOUNTED_INTERIX_STATVFS.
+
+2013-10-06  Paul Eggert  <eggert@cs.ucla.edu>
+
+	tests: improve diagnostic when an assertion fails
+	* tests/macros.h (ASSERT): Report the assertion that failed.
+
+2013-10-02  Paul Eggert  <eggert@cs.ucla.edu>
+
+	verify: new macro 'assume'
+	This is taken from Emacs, and should be generally useful.
+	* doc/verify.texi (assume): Document it.
+	* lib/verify.h (assume): New macro.
+	(__has_builtin): Expand to 0 if not defined.

+	dup2, dup3: work around another cygwin crasher
+	* m4/dup2.m4 (gl_FUNC_DUP2): Expose the bug.
+	* m4/dup3.m4 (gl_FUNC_DUP3): Likewise.
+	* tests/test-dup2.c (main): Likewise.
+	* lib/dup2.c (rpl_dup2): Use setdtablesize to avoid it.
+	* lib/dup3.c (dup3): Likewise.
+	* doc/posix-functions/dup2.texi (dup2): Document it.
+	* doc/glibc-functions/dup3.texi (dup3): Likewise.
+
+	getdtablesize: work around cygwin issue
+	* m4/getdtablesize.m4 (gl_FUNC_GETDTABLESIZE): Detect problem.
+	* modules/getdtablesize (configure.ac): Build replacement.
+	* m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Set up a witness.
