[Qemu-devel] [RFC 06/12] target-ppc: Eliminate Unused Variable in decSetSubnormal

[Tom Musta <tommusta@gmail.com>]

This patch eliminates an unused variable in the decSetSubnormal
routine.  The variable dnexp is declared and eventually set but
never used.  This triggers a unused-but-set-variable warning, which
can fail QEMU compilation.
