--- Begin Message --- Subject: Re: bug#66709: gzip build fails on s390x because (version 1.13) Date: Mon, 23 Oct 2023 14:45:21 -0700 User-agent: Mozilla Thunderbird Thanks for the bug report. This bug was introduced during the flurry of patches just before 1.13 was released. Commit d826f7c04d824362dd1ba91c13d8f2c8b0996fff dated Sat Aug 19 11:23:45 2023 -0700 removed Gnulib's stdalign module but did not add Gnulib's alignasof module that replaced stdalign. gzip needs this module because gzip.c and (as you noticed) dlftcc.c use alignas. We didn't notice the bug until now because gzip.c falls back on working code if alignas is absent, and we don't test on s390x.

I fixed the bug by installing the attached, which should appear in the next gzip release. In the meantime you should be able to build on s390x by compiling with 'gcc -Dalignas=_Alignas'.
