+       Pacify "gcc -Wunused" for the input function from Flex.
+       Reported by Alex Rozenman.  This warning shows up with gcc-4.3.0
+       and later.
+       * src/scan-code.l: Add "%option noinput", which I cannot find in
+       the Flex manual, but which Flex has supported since at least as
+       far back as 2.5.4.  However, if any of our developers still use
+       Flex 2.5.4, they'll need to stop configuring with
+       --enable-gcc-warnings because "%option noinput" didn't work
+       correctly until Flex 2.5.6.
+       * src/scan-gram.l: Likewise.
+       * src/scan-skel.l: Likewise.

+       build: avoid concurrent extraction of calc++.
+       * examples/calc++/Makefile.am (calc.stamp): New.
+       Depend on it to create the sources of calc++ so that concurrent
+       builds don't launch several "extexi" in parallel.
+       Not only this is inefficient, this also builds incorrect sources
+       with several extractions mixed together.

+       hash: check insertion for memory exhaustion.
+       * src/uniqstr.c (uniqstr_new): New.
