-/* The macro PAGE_COPY_FWD_MAYBE defined in memcopy.h is used in memmove if the
-   PAGE_COPY_THRESHOLD macro is set to a non-zero value.  The default is 0,
-   that is copying by pages is not implemented.
-
-   System-specific pagecopy.h files that want to support page copying should
-   define these macros:
-
-   PAGE_COPY_THRESHOLD
-   -- A non-zero minimum size for which virtual copying by pages is worthwhile.
-
-   PAGE_SIZE
-   -- Size of a page.
-
-   PAGE_COPY_FWD (dstp, srcp, nbytes_left, nbytes)
-   -- Macro to perform the virtual copy operation.
-   The pointers will be aligned to PAGE_SIZE bytes.
