configure.ac: consider adding -Wall and silent rules for automake

[GoogleCodeExporter]

Consider adding -Wall (and possibly also -Werror) to either AUTOMAKE_OPTIONS in 
Makefile.am or as an argument to AM_INIT_AUTOMAKE.

If you don't mind using a modern automake (1.11 or later), you can also call 
AM_SILENT_RULES([yes]), but makes the generated makefiles require the 
"non-POSIX, but in practice rather widely supported Makefile construct of 
nested variable expansion ‘$(var1$(V))’" (cite: 
http://www.gnu.org/software/automake/manual/html_node/Options.html#Options ). 
Even MSYS has automake-1.11 these days.
