Message : 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

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.
