Test and Install the Machine-Dependent Routines.

There are five machine-dependent functions in the test and timing package, at least three of which must be installed. They are


LSAME 		  LOGICAL 		 Test if two characters are the same regardless of case 

SLAMCH REAL Determine machine-dependent parameters
DLAMCH DOUBLE PRECISION Determine machine-dependent parameters
SECOND REAL Return time in seconds from a fixed starting time
DSECND DOUBLE PRECISION Return time in seconds from a fixed starting time
ILAENV INTEGER Checks that NaN and infinity arithmetic are IEEE-754 compliant

If you are working only in single precision, you do not need to install DLAMCH and DSECND, and if you are working only in double precision, you do not need to install SLAMCH and SECOND. These five subroutines and their test programs are provided in the files LSAMEF and TLSAMEF, SLAMCHF and TSLAMCHF, etc.
