Was any code changed to keep the library internal name and global
constructors for the library consistent?  If not, the problem is
likely to occur again.  It's quite annoying to have to rebuild all
apps linked against the library when you ugrade gcc.  That's why I
didn't close the PR when I added to the audit trail.
