libaec provides fast lossless compression of 1 up to 32 bit wide
signed or unsigned integers. It implements the Golomb-Rice compression
method under the BSD license and includes libsz, a drop-in replacement
for the SZIP library with the same API (szlib.h) and soname
(libsz.so.2).

szip is not maintained upstream anymore: 2.1.1 is the last release,
there is no public repository, and the source is only available from
the HDF Group archive. Its license is not a standard open source one,
and the HDF Group itself recommends libaec as a replacement.
The package also fails to build with GCC >= 15 on non-glibc
toolchains, as only linux-gnu hosts get -ansi from szip's configure
and the code relies on pre-C23 empty parameter lists:
rice.c:1323:15: error: too many arguments to function 'winner_ref_function'; expected 0, have 2
libaec provides libsz, a drop-in replacement with the same API and
soname, so select it through the legacy option.
Fixes:

- Szip is an implementation of the extended-Rice lossless
- compression algorithm.
-
- The Consultative Committee on Space Data Systems (CCSDS) has
- adopted the extended-Rice algorithm for international
- standards for space applications[1,6,7]. Szip is reported to
- provide fast and effective compression, specifically for the
- EOS data generated by the NASA Earth Observatory System
- (EOS)[1]. It was originally developed at University of New
- Mexico (UNM) and integrated with HDF4 by UNM researchers and
- developers.
