Much of apr_app_initialize performs manipulation of environment variables (in
particularly converting them from Unicode to char*).  Since WinCE doesn't have
environment variables and GetEnvironmentStringW or FreeEnvironmentStringsW, it
is simplest just to #if most of that code out.

apr_app_initialize also update the argv array by parsing the Unicode command
line which uses the CommandLineToArgvW API method which is not available on
WinCE (and not in the Win32 API documentation).  In the patch, the code which
gets the Unicode command line, parses and updates the ASCII argv array is
suppressed on WinCE.
