Not quite. The syntax for giving a C++ static object a constructor
priority has always been __attribute__ ((init_priority (<num>))),
since that functionality was added back in 1997 or so. However early
on this syntax was only accepted if you also specified -finit-priority
on the command line. If you tried to use an init_priority attribute
without -finit-priority then the compiler would give an error or
something like that - I don't remember the exact details.

It did not take long before the init_priority attribute was considered
mainstream rather than experimental. Hence the compiler was changed so
that it would always accept the attribute, irrespective of whether or
not -finit-priority was specified on the command line. So
-finit-priority no longer served any purpose. It was kept around for a
while for compatibility reasons, but removed recently as part of a
more general clean-up of compiler command-line options.
