Compilation Warnings on OS X 10.5

Compilation Warnings on OS X 10.5

I received a number of "-Wshadow" related warnings (treated as errors) while
trying to build on OS X Leopard.  In addition, there were two miscellaneous
other warnings in the flash drivers.  Attached are two patches which correct
these issues and the commit messages to accompany them.

My system has the following configuration (taken from uname -a):

Darwin 9.8.0 Darwin Kernel Version 9.8.0: Wed Jul 15 16:55:01 PDT 2009;
root:xnu-1228.15.4~1/RELEASE_I386 i386

=== Werror_patch.txt Commit Message ===
