ok, so I compiled gsl using icc by setting the CC environment variable 
to icc using the tcsh.
compilation is not the problem, but make check yields the following:

...
 PASS: gsl_isinf(0) (0 observed vs 0 expected)
PASS: gsl_isinf(1) (0 observed vs 0 expected)
FAIL: gsl_isinf(inf) (0 observed vs 1 expected)
FAIL: gsl_isinf(-inf) (0 observed vs -1 expected)
PASS: gsl_isinf(nan) (0 observed vs 0 expected)
PASS: gsl_isnan(0) (0 observed vs 0 expected)
PASS: gsl_isnan(1) (0 observed vs 0 expected)
PASS: gsl_isnan(inf) (0 observed vs 0 expected)
FAIL: gsl_isnan(nan) (0 observed vs 1 expected)
PASS: gsl_finite(0) (1 observed vs 1 expected)
PASS: gsl_finite(1) (1 observed vs 1 expected)
FAIL: gsl_finite(inf) (1 observed vs 0 expected)
FAIL: gsl_finite(nan) (1 observed vs 0 expected)
PASS: gsl_fdiv(2,3) (0.666667 observed vs 0.666667 expected)
FAIL: test

switching off optimisation by using the -O0 option doesn't cure that 
behaviour.

using gcc there is no problem at all.

system: SuSE-7.3 on athlon-MP
