[ts-gen] trading-shim now compiles under g++4

There is good news; the sources now compile under both our current gcc3
environment and in addition under gcc4 as well.

I'll stick with the former until the std Centos g++ goes to gcc4, however,
in part because using distcc requires identical headers on each member of the
server farm, and I'll give up distcc when you pry my cold, dead fingers ... you
get the idea.  We expect to go to gcc4 internally sometime in Dec or Jan, in
parallel with Centos itself.

So those of you using a ver 3 g++ don't need to worry, you are using the
same level compiler as we are, the code still compiles with no problems,
and this just means that the upcoming version change to 4 should be
painless.

As for those of you on Debian, or bleeding edge Fedora boxes, feel free to
compile under gcc4, and please speak up if you have trouble.

By the way, the fixes, though semantically empty, are textually substantial,
that is though they mostly boil down to keeping the compiler happy with
explicit namespaces and revised declarations, still much of the source text
is affected.  This means that if you are attempting to modify the sources, you
really, *really* want to follow along here; due to the sheer bulk of the type
related changes, the further you diverge, the more effort it will take to
rejoin later.

Thanks,

Bill
