More updates and cleanups on autotools and Makefiles

Makefile.am, example/Makefile.am:

* Replaced the obsolete INCLUDES variable with AM_CPPFLAGS/AM_CFLAGS

acinclude.m4:

* autoupdate replaced AC_FD_CC with AS_MESSAGE_LOG_FD

autogen.sh:

* Added -Wall to the autoreconf invocation, which turned up a whole slew
   of warnings that are fixed by this patch

configure.in:

* Most of the changes are due to autoupdate, with subsequent manual
   tidying

* Note that autoupdate bumped the AC_PREREQ version from 2.59 to 2.68. If
   you normally use an older version of Autoconf, and everything works fine
   if you comment out that directive, feel free to bump down the version
   accordingly.

* Ensure that #include directives in C fragments always have no whitespace
   to the left of the '#' mark, as some preprocessors need that to be in
   the first column

example/Makefile.am:

* Don't need DEPS

* Use plain LDADD instead of LDADDS; if all programs in this file need to
   link against the same set of libraries, then this is all you need

acinclude.m4

dnl Like AC_TRY_EVAL but also errors out if the compiler generates
dnl _any_ output. Some compilers might issue warnings which we want
dnl to catch.
