I guess you know there are patches for waiting in patch tracker, the
most recent one by Kostia from August.

The compression is used to compress debugging information, AFAIK. We
do not need the information (yet).

I added some basic and limited ELF reading code to allow loading ELF
files when compiling using MS Visual Studio [1]. We might drop the
libbfd dependency and use our private implementation (that would
require enhancing my code). Brandon may use this one. I was stuck last
weekend trying to compile under Linux, I will post my notes and
workaround separately.

In future I will need some more complete ELF reading code for my other
projects. I have been toying with ELFIO library, but there is too much
object-oriented mumbo-jumbo. I would welcome recommendations which
compile under MSVC or can be modified to compile.
