If you call ILAENV(10, ...), it will check IEEE Infinity and IEEE NaN behavior.
No need to call ILAENV(11, ...)

Note that the call to IEEE = ( ILAENV( 10, 'SLASQ2', 'N', 1, 2, 3, 4 ).EQ.1 )
in SLASQ2 is commented out with the following comment:
*
*     [11/15/2008] The case IEEE=.TRUE. has a problem in single precision with
*     some the test matrices of type 16. The double precision code is fine.
*
and IEEE is set to .FALSE.
