The commercial software I make my living from includes a library plus some
console mode programs which use the library. Both programs and library
must be highly portable, so don't include <windows.h>. No use of
multi-threading originally, although a set of programming practices were
followed which tended to make the code thread-safe.

I've had good luck turning one of the programs into a multi-threaded app
using a early version of Boost.Threads. Worked first try on both single
and multi-processor machines.

It would certainly cause concern if windows.h was included. That has
happened inadvertently a few times in the past, and caused (minor)
problems. It also means certain failures won't show until porting to other
platforms, which is viewed as a bad thing.

For this type of very portable software, including windows.h in the public
Boost.Thread headers would be seen as a bit of a reduction in
quality-of-implementation. Not a showstopper, however.
