New submission from Felix Yan <[email protected]>:
In bpo-40874, mpdecimal.h in the vendored libmpdec has defines of UNUSED while
the standalone released version of mpdecimal 2.5.0 doesn't. This breaks
_decimal module build with system libmpdec due to UNUSED is undefined.
Errors are like:
cpython/Modules/_decimal/_decimal.c:277:36: error: expected ‘;’, ‘,’ or ‘)’
before ‘UNUSED’
277 | dec_traphandler(mpd_context_t *ctx UNUSED) /* GCOV_NOT_REACHED */
| ^~~~~~
Reproducible in both 3.8 branch and master (didn't test 3.9, but should be
affected too).
