- setup.patch: fix use of unknown compiler option
-------------------------------------------------------------------

- Update to 1.2.4
- Updated to c-blosc 1.4.0. This added support for non-Intel
architectures, most specially those not supporting unaligned access.

- Update to 1.2.3
- Updated to c-blosc 1.3.5. This removed a 'pointer from integer
without a cast' compiler warning due to a bad macro definition.
- Update to 1.2.2
- Updated to c-blosc 1.3.4. This fixed a false buffer overrun
condition. This bug made c-blosc (and hence python-blosc) to fail,
even if the failure was not real.
- Update to 1.2.1
- Updated to c-blosc 1.3.3.
- Added a new `cname2clib` map for programatically determine the library
associated to a compressor.
- New `get_clib(cbuffer)` that tells which compression library format
has been used to created the compressed `cbuffer`.
- Update to 1.2.0
- This release adds support for the multiple compressors added in Blosc
1.3 series.
- Added new `cname` parameter in compression functions like
`compress()`, `compress_ptr()` and `pack_array()`.
- Added a new utility function named `compressor_list()` that returns
the list of compressors supported in the Blosc build.
- Added 'bench/compress_ptr.py' for comparing times of the different
compressors in Blosc and NumPy.
- Update to 1.1.0
- Added new `compress_ptr` and `decompress_ptr` functions that allows to
compress and decompress from/to a data pointer. These are low level
calls and user must make sure that the pointer data area is safe.
- Since Blosc (the C library) already supports to be installed as an
standalone library (via cmake), it is also possible to link
python-blosc against a system Blosc library.
- The Python calls to Blosc are now thread-safe (another consequence of
recent Blosc library supporting this at C level).
- Many checks on types and ranges of values have been added. Most of
the calls will now complain when passed the wrong values.
- Docstrings are much improved. Also, Sphinx-based docs are available
now.
- Update to 1.0.6
- Fix compile error with msvc compilers. Thanks to Christoph Gohlke.
- Update to 1.0.5
- Upgraded to latest Blosc 1.1.4.
- Better handling of condition errors, and improved memory releasing in
case of errors (thanks to Valentin Haenel and Han Genuit).
- Better handling of types (should compile without warning now, at least
with GCC).
- Update to 1.0.4
- Optimized the amount of data copied during compression (using
_PyBytes_Resize() now instead of old PyBytes_FromStringAndSize()).
This leads to improvements in compression speed ranging from 1.2x for
highly compressible chunks up to 7x for mostly uncompressible data.
Thanks to Valentin Haenel for this nice contribution.
- Use external blosc library. The internal one builds a bad version
of zlib.
