/* libpthread used to have its own vfork implementation that differed
   from libc's only in having a pointless micro-optimization.  There
   is no longer any use to having a separate copy in libpthread, but
   the historical ABI requires it.  For static linking, there is no
   need to provide anything here--the libc version will be linked in.
   For shared library ABI compatibility, there must be __vfork and
   vfork symbols in libpthread.so.  */
