+	feenv_nomask_test, feenv_mask_test, feexcp_nomask_test,
+	feexcp_mask_test, feenable_test, fe_single_test): Add
+	[!FE_ALL_EXCEPT] test so these routines are not compiled in the
+	case where they are not used.
+	* math/libm-test.inc: Likewise.
+	* setjmp/test-setjmp-fp.c: Mark attribute ((unused)) on variable
+	unused in the absence of FP rounding/exception support.
+	* stdio-common/tst-printf-round.c: Likewise.
+	* stdlib/tst-strtod-round.c: Likewise.
+	* stdlib/tst-strtod-underflow.c: Likewise.
