@file posh.h
@author Brian Hook
@version 1.3.001
Header file for POSH, the Portable Open Source Harness project.
NOTE: Unlike most header files, this one is designed to be included
multiple times, which is why it does not have the @#ifndef/@#define
preamble.
POSH relies on environment specified preprocessor symbols in order
to infer as much as possible about the target OS/architecture and
the host compiler capabilities.
NOTE: POSH is simple and focused. It attempts to provide basic
functionality and information, but it does NOT attempt to emulate
missing functionality. I am also not willing to make POSH dirty
and hackish to support truly ancient and/or outmoded and/or bizarre
technologies such as non-ANSI compilers, systems with non-IEEE
floating point formats, segmented 16-bit operating systems, etc.
Please refer to the accompanying HTML documentation or visit
http://www.poshlib.org for more information on how to use POSH.

REVISION:
I've been lax about revision histories, so this starts at, um, 1.3.001.
Sorry for any inconveniences.
1.3.001 - 2/23/2006 - Incorporated fix for bug reported by Bill Cary,
where I was not detecting Visual Studio
compilation on x86-64 systems. Added check for
_M_X64 which should fix that.
