+       count-leading-zeros: use a lookup table on non-gcc compilers
+       * lib/count-leading-zeros.h (count_leading_zeros_32): Use an
+       alternate implementation, suggested by Jim Meyering.

+       * m4/count-leading-zeros.m4: New file.
+       * lib/count-leading-zeros.h: Likewise.
+       * modules/count-leading-zeros-tests: New test.

+       extern-inline: also ignore -Wmissing-declarations
+       * m4/extern-inline.m4: Also ignore -Wmissing-declarations,
+       required with gcc-4.8.0-to-be.
+
+       maint.mk: sc_prohibit_magic_number_exit: avoid new false positives
+       * top/maint.mk (sc_prohibit_magic_number_exit): Also filter out matches
+       for /error ?([^,]*)/.  This avoids false-positives for strings like
+       "Unknown error (252)", introduced via commit v0.0-7538-g92875a6.

+
+       gnumakefile: better interaction with Automake-NG
+       * modules/gnumakefile [Makefile.am]: The makefiles generated by
+       Automake-NG always contain a definition of VPATH, even in non-VPATH
+       builds (its value being simply '.' in that case).  So, in the
+       'clean-GNUmakefile' rule, to determine whether running under a
+       VPATH setup, compare '$(srcdir)' to '.' rather than checking whether
+       '$(VPATH)' expands to the empty string.

+
+       base64: Use extern C scope in header file, for C++.
+       * lib/base64.h: Add C++ namespace protection.
