+O4 enables link time global optimizations over the whole executable, beyond
the file level optimization that is done during compilation. That
global optimization takes a long long time on a library with this many
functions in it, which is why your make seemed to hang. Be patient and
it'll finish eventually.
The global optimizations include automatic inlining of functions, which
isn't always safe but is safe in this case. The warnings are just the
linker's way of reminding you to think about it. Ignore them.
