 * $Workfile: etypes.h $

 *
 * PURPOSE:
 * Base types that are used in machine independent APIs.
 * The types declared here are intended to describe variables of known sizes
 * so that there will be no ambiguity in setting up the stack for a function
 * call.
 * 
 * ASSUMPTIONS:
 * All pointers are FAR in Windows.  Please include the FAR macro for every
 * pointer reference.
 *
 * NOTE:
 * Sizes of types:
 * Types that have ambigious sizes are left out of this file.  You will not
 * find int nor float.  Types that may not be the same size on all platforms
 * also tend to drop out of this file (eg. short.)
 * whar_t presents a problem.  wchar_t is has the same size and alignment
 * as int, therefor it's size may vary from compiler to compiler!
 * We will represent pointers to wchar_t as pointers to uint8 
 *
 * Floats as return values from functions:
 * Microsoft and Borland do not seem to return floats and doubles
 * in the same way from functions.  As a result of this, please do
 * not construct a function as part of a public DLL API that returns
 * a float or double.  If the calling application was not made with a 
 * compiler that has the same assumptions about floating point returns,
 * a difficult to find error may develop. - becd.
