/**
 * Isolate here the differences between ANSI string and memory functions and
 * Palm string and memory functions.  Note the sml tree contains similar
 * mappings, but we avoid those for two reasons:
 *
 *  1. They are all implemented as functions, which makes calling them less
 *     efficient, especially on the Palm.  Also, if they are implemented as
 *     functions, then the xpt DLL and the DLLs of all transport
 *     implementations must be linked to the sml DLL, which seems unnecessary.
 *
 *  2. Even on the Palm, the libstr.h and libmem.h header files include ANSI C
 *     header files like string.h and stdlib.h.  These shouldn't be included
 *     on the Palm, because with some compilers, the introduced typedefs
 *     conflict with typedefs from the Palm SDK, causing compilation errors.
 *
 * We start the names of these functions with a different prefix so they are
 * not confused with functions of the official xpt interface.  We use "xpp"
 * here instead of "xpt".
