  78   The db4 c++ library by default tries to link against libpthread on some
  79   systems (notably Linux).  If your PHP install is not linked against
  80   libpthread, you will need to disable pthread support in db4.  This can
  81   be done by compiling db4 with the flag  --with-mutex=x86/gcc-assembly.
  82   PHP can itself be forced to link against libpthread either by manually editing
  83   its build files (which some distributions do), or by building it with
  84   --with-experimental-zts.])
