Hi,
OpenJDK 8 will not build under C2y (C26?) or with the next glibc
any more. Are you going to fix this upstream?
The options are probably probing for it and using the standard
function when present, or renaming it and always using the own.
Thanks in advance,

Subject: Bug#1115228: openjdk-8: FTBFS with glibc 2.42 due to conflict with the
newly added uabs function
Source: openjdk-8
Version: 8u462-ga-1
Severity: important
Tags: ftbfs forky sid
Justification: fails to build from source
User: debian-glibc at lists.debian.org
Usertags: glibc-2.42
Dear maintainer,
During a rebuild of all packages in unstable with glibc 2.42 from
experimental, your package failed to build. Below you will find how the
build ends. If required, the full build log is available here:
https://people.debian.org/~aurel32/glibc-2.42/
The build failure is due to the addition of the uabs function (part of
ISO C2Y) to glibc 2.42, now conflicting with the openjdk source code:
https://sourceware.org/git/?p=glibc.git;a=blob;f=NEWS;h=f0b0e924a45c7698e6ca6415f2d9a096a24e37df;hb=d2097651cc57834dbfcaa102ddfacae0d86cfb66#l22
About the archive rebuild: The build was made on virtual machines from
AWS, using sbuild, a reduced chroot with only build-essential packages
and glibc 2.42 from experimental.
Regards
Aurelien
