# (and libfuse_ino64, by extension) don't link in libiconv. This wouldn't
# be a problem, but it appears the Darwin/OS X dynamic linker won't
# satisfy runtime link dependencies in those libraries from libraries
# imported by our library, and it uses a symbol from libiconv without
# actually linking the library to itself. Awesome.
