-  PDC_copy_win() - Common routine for copywin(), overlay() and 
-	overwrite() functions.
-
-  PDCurses Description:
-	This function copies the region of the source window specified
-	over the specified region of the destination window. All 
-	validation of limits are done by the calling function.
-
-	Thanks to Andreas Otte (venn@uni-paderborn.de) for the code 
-	changes.
-
-  PDCurses Errors:
-	ERR is returned if either src or dst windows are NULL;
-
-  Portability:
-	PDCurses  int PDC_copy_win(const WINDOW *src_w, WINDOW *dst_w,
-			int src_tr, int src_tc, int src_br, int src_bc,
-			int dst_tr, int dst_tc, bool overlay);
