I don't think that it is #define-d in any header file, but instead
magically appears in the CL command-line depending on the build
configurations used in eVC++.  So, trying to use it in VC++, as above,
will not work.  There is some more information here, under the heading
"The $(CePlatform) Macro":
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnppc2k
/html/ppc_ource.asp  You can see the following in the eVC++ screenshot:
"... /D _WIN32_WCE=$(CEVersion) ...".

We always use it something like this:

#ifdef _WIN32_WCE
#if _WIN32_WCE < 300

...

#endif
#endif
