Nothing changed in the library code for integers, lately, and, moreover, as far
as I can see, the test started failing exactly around 2007-04-06, when I
changed that code involved only with floats. Moreover, for integers, there is
nothing target-specific in the library, and the other targets (hppa-linux
included) are fine. I'm going to commit my changes, which are needed, anyway,
but, missing additional info, I cannot do more, I have absolutely no clues.
Maybe it's just a miscompilation, you should try to compile both library and
testcase at lower optimization level, as a first check.
