jdk build fails due to "warning: ‘readdir_r’ is deprecated"

[Thomas Stüfe]

Hi all,

maybe someone has an idea:

I build on a freshly installed Linux instance (MX17), using gcc 6.3.0.

I get this error:

Creating support/modules_cmds/jdk.pack/unpack200 from 7 file(s)
/shared/projects/openjdk/jdk-hs/source/src/jdk.management/unix/native/libmanagement_ext/OperatingSystemImpl.c:

            ^~~~~~~~~

I digged and was not able to pin it to any recent change. I also think  I
never successfully built on this box, so it may be my environment.

Could it be that my gcc is too new?

Thanks! Thomas
