@mhillen Thanks, I'm doing the package renames in LP: #1915927. This is minimally intrusive, but breaks not packaged software, they need to be rebuilt.

The upcoming glibc release 2.33 will be a first step towards cleaning that up, which will change float_t to become float on s390x when compiling C++ code, such as in clucene- core. That would break the ABI of clucene-core on s390x for existing binaries. Today, clucene-core uses float_t for some parameters in its API; that type is defined as double on s390x today. Together with gcc's default behavior, that contradicts the C standard. To get to a more sane combination, the upcoming glibc release 2.33 will change float_t to become float on s390x (with some exceptions when compiling C code, which do not apply for clucene-core). To my knowledge, glibc 2.33 is a candidate for inclusion in Ubuntu 21.04. To avoid breaking the API of clucene-core in the process, I have prepared a trivial patch that fixes clucene-core's API to always use double instead of float_t on s390x. That patch effectively persists the current de-facto API on s390x, without changes for other architectures. Note that using float_t in an API is generally "not a great idea", because that type can have different definitions even with the same compiler and glibc version on the same system (e.g., on 32-bit x86, when switching between SSE and x87 FP ops). Patch submitted in https://sourceforge.net/p/clucene/bugs/233/ and https://sourceforge.net/p/clucene/mailman/message/37153930/ yet upstream clucene is effectively unmaintained. If Ubuntu 21.04 adopts glibc 2.33, please consider pulling in this patch in clucene-core.
