Ah, looks like sysdeps/ia64/fpu is in need of a refresh. v2.1 of the Intel libm for Itanium does have exp2l (and log2l was introduced in verison 1.4). Can somebody clue me in on the meaning of the various math-library file-name prefixes? "w_" stands for "wrapper", I figured that one. But what's the idea behind the "s_" vs. "e_" prefixes? --david
