Oracle Solaris 11.4 Linker and Libraries Guide: https://docs.oracle.com/en/operating-systems/solaris/oracle-solaris/11.4/linkers-libraries/version-symbol-section.html defines VER_NDX_LOCAL to 0 with a comment, "Symbol has local scope". This leads to different interpretations by different linker implementations. However Solaris as well as ld and ld.so in glibc always treat symbols with version index 0 as unversioned symbols with global binding. As discussed in https://sourceware.org/bugzilla/show_bug.cgi?id=33577 in hindsight, VER_NDX_NONE might be a better name. Ali from Oracle is working on clarifying what version index 0 really means for unversioned symbols with global binding. In the meantime, update gold to treat symbols with version index 0 as unversioned with global binding. elfcpp/ PR gold/33577 * elfcpp.h (VER_NDX_LOCAL): Update comments.

elfcpp is a C++ library for reading and writing ELF information. This
was written to support gold, the ELF linker, and may not be generally
useful.
elfcpp does not do file I/O. It deals only with offsets and memory
data.
For efficiency, most accessors are templates with two arguments: the
ELF file class (32 or 64 bits) and the endianness.
