	Configure tries to figure out how to print `long long' types
	and then defines PRINTF_LL_WIDTH to be `ll' or `q' or
	something.  It does this by running little sprintf() programs
	with various formats until it gets one that works.  If this
	causes problems when cross compiling (like with parallel
	machines) then you may add the following to the appropriate
	config file:

	       hdf5_cv_printf_ll=${hdf5_cv_printf_ll='ll'}	or
	       hdf5_cv_printf_ll=${hdf5_cv_printf_ll='q'}	or
	       hdf5_cv_printf_ll=${hdf5_cv_printf_ll='l'}


./config/intel-osf1
./config/irix5.3
	Updated these config files to match the others.  This allows
	the `--enable-production' configure flag to work properly.
