*fpieee.h - Definitions for floating point IEEE exception handling
*
*       Copyright (c) 1991-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
*       This file contains constant and type definitions for handling
*       floating point exceptions [ANSI/IEEE std. 754]
*
*       [Public]
*
*Revision History:
*       03-01-92  GDP   written
*       04-05-92  GDP   calling convention macros
*       01-21-93  GJF   Removed support for C6-386's _cdecl.
*       04-06-93  SKS   Replace _CRTAPI1/2 with __cdecl, _CRTVAR1 with nothing
*       09-01-93  GJF   Merged Cuda and NT SDK versions.
*       09-24-93  GJF   Removed dummy args from _fpieee_flt prototype.
*       01-13-94  RDL   Added #ifndef _LANGUAGE_ASSEMBLY for asm includes.
*       01-24-94  GJF   Merged in 01-13 change above (from crt32 tree on
*                       \\orville\razzle).
*       11-03-94  GJF   Ensure 8 byte alignment.
*       02-11-95  CFW   Add _CRTBLD to avoid users getting wrong headers.
*       02-14-95  CFW   Clean up Mac merge.
*       12-14-95  JWM   Add "#pragma once".
*       02-21-97  GJF   Cleaned out obsolete support for _CRTAPI* and _NTSDK.
*                       Also, detab-ed.
*       09-30-97  JWM   Restored not-so-obsolete _CRTAPI1 support.
*       10-07-97  RDL   Added IA64.
*       09-11-98  JWM   Added Katmai exception support.
*       05-13-99  PML   Remove _CRTAPI1
*       05-17-99  PML   Remove all Macintosh support.
*       03-01-00  PML   Add WNI exception support.
*       09-14-00  PML   Add alignment for 64-bit, 128-bit types (vs7#160260).
*       03-24-01  PML   Enable 64-bit/128-bit type alignment on x86.
