redirect it to a file that we can dump later on cache hits.  Parts
of this change are extracted from code from Pierre Parutto
<parutto@lrde.epita.fr>.

to suppress a GCC warning.

type of stream_compression_base<int_array_array_compression> in
constructor to please g++ versions <= 4.3.

* iface/dve2/dve2.cc (dve2_state, dve2_compressed_state): Store
size and count on 16 bits, and hash on 32 bits, to limit memory
wasted.

* src/tgbatest/intvcomp.cc: Test them.
* src/sanity/style.test: Refine check to avoid a spurious report.

* configure.ac: Do not add CXXFLAGS and CFLAGS in ac_configure_args,
it causes problem when using config.cache.  Instead ...
* m4/devel.m4: Add --enable-devel or --disable-devel on
ac_configure_args, now that BuDDy understands that.

Fix some warnings reported by gcc.
