Hi,

The target_read_memory function pointer that
bfd_elf_bfd_from_remote_memory accepts current accepts int for length.
I have attached a patch which changes this argument to size_t. This
change is needed because I'm looking to make analogous changes in gdb to
ensure consistency of storage sizes passed across functions to ensure
that larger values are not truncated.

I could write a wrapper around or cast the function pointer explicitly,
but as Jan Kratochvil suggested, it would be cleaner to just make a
change in bfd since it should be taking size_t values anyway. The
conversation thread is here for reference:

http://sourceware.org/ml/gdb-patches/2012-05/msg00909.html

Attached are two patches, the first being changes to bfd and the second
is the change I need to make in gdb to make it work with the changes in
bfd.

Regards,
Siddhesh
