Both sin and sinf are assembly routines so can't probably be affected by
the gcc used to compile them.  See sysdeps/i386/fpu/s_sinf.S and
sysdeps/i386/fpu/s_sin.S.

I have not seen a working library for your testcase (2.9, built with
GCC 4.3.2 is broken).

This isn't a GCC bug but a glibc bug.  Clearly glibc uses fsin out of specs.
