Product(s): Microsoft C Compiler
Version(s): 6.0
Operating System(s):

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows CE Toolkit for Visual C++ 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Building a MIPS-based Palm-size PC application that uses floating-point
comparisons may generate errors similar to the following:

  project.obj : error LNK2001: unresolved external symbol __ltd
  project.obj : error LNK2001: unresolved external symbol __gtd
  project.obj : error LNK2001: unresolved external symbol __eqd

CAUSE
=====

The new version of the MIPS compiler for the Palm-size PC incorrectly makes
calls to floating-point comparison functions in later versions of the Windows CE
C run time.

RESOLUTION
==========

Use the /QMOC switch to call the earlier versions of the Windows CE
floating-point comparison functions.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.

MORE INFORMATION
================

Steps to Reproduce Behavior
---------------------------

The following code fragment generates the errors listed in the SYMPTOMS section:

      double  a, b;

      if ( a < b ) return -1;
      if ( a > b ) return 1;
      if ( a==b ) return 0;
