dnl ...
dnl
dnl Organization:
dnl 1. Autoconf dependencies (autoconf version/automake version)
dnl 2. Special options that need to be checked before compiler tests
dnl 3. Basic prerequisites (compiler tests, tools, system, etc.)
dnl 4. Host-specific settings and tests
dnl 5. Process and test --with/--enable options (which may need the host-specific settings)
dnl 6. Generate output

dnl Autoconf dictionary:
dnl build : platform on which the package is configured and
dnl compiled. Defaults to the result of running config.guess.
dnl host : platform on which the package runs. Defaults to build.
dnl target: platform for which any compiler tools in the package
dnl produce code (rarely needed). Defaults to host.
