I am unable to read the files you have included in your email -- can you resend
them as MIME attachment, not as UUECODE something? 

I don't see any reason for behaviour your observe. However -- are you sure you
are looking at compile lines in both cases, and not on linker command line
in one case?  The /Wp64 switch is only used for compilation. Note that it
is also used when <warnings>all property is specified.
