I confirm glibc 2.13 built with gcc 4.6.1 20110408 snapshot patched with
gcc46-pr48597.patch results in correct unwind info for __ieee754_lgammaf_r. I
checked all the locations using (v)movd %xmmN,%ebp pattern, and the unwind info
is now correct everywhere. Haven't run any of the newly compiled code yet, will
do that later.
