I see what you are saying now.  I had to look back at his code.  I
answered the way I did because I only looked for the #ifdef/#endif
combination and assumed that he put the function in there because it WAS
being called.  As such, it looks like a memory layout problem that could
be related to the libraries or the compiler/OS combination.
