Building either editors/openoffice-4 ore editors/openoffice-devel on either amd64 or i386 fails with these linker errors:

Building with older llvm from ports avoids this problem.

I will try to put together an upstream bug report.

    editors/openoffice-*: Unbreak build on 15.0-CURRENT

    clang version 17.0.6 causes linker errors that break the build on
    15.0-CURRENT.  Work around this by building with an older llvm from
    ports.

It turns out that the --no-undefined-version change is the culprit.

In this particular case, GetVersionInfo is only exported by the Windows and OS/2 builds, so I have no idea why it is including in the .map file being used by the linker.  Both _ZN9salhelper9ConditionC1ERN3osl5MutexE and _ZN9salhelper9ConditionC2ERN3osl5MutexE are listed in the .map (do accommodate a name mangling variation?) but only one of those symbols is defined.
