@ 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 .
