+ 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.
