+       Improve support for popcount and counting trailing zeros (Bug#15550).
+       Do this by using the Gnulib modules for this.
+       This should generate faster code on non-GCC, non-MSC platforms,
+       and make the code a bit more portable, at least in theory.
+       * lib/count-one-bits.c, lib/count-one-bits.h:
+       * lib/count-trailing-zeros.c, lib/count-trailing-zeros.h:
+       * m4/count-one-bits.m4, m4/count-trailing-zeros.m4:
+       New files, copied from gnulib.
+       * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
