For developers
--------------
The build specifies C99 conformance, all compiler warnings turned on,
and all warnings considered errors (compiler options ``-std=c99
-Werror -Wall``).
By default, ``CFLAGS`` is set to ``-g -O2``, so that symbols are
included in the shared library, and optimization is at level
``O2``. To change or disable these options, set ``CFLAGS`` explicitly
before calling ``make`` (it may be set to the empty string).
For development/debugging cycles, the ``configure`` option
``--enable-debugging`` is recommended (off by default). This will turn
off optimizations and function inlining, so that a debugger will step
through the code as expected.
