+/* On Windows, jpipe.dll must not have dependencies on any other URE DLLs, as

+   this code goes into a jpipx.dll that the jpipe.dll wrapper loads with
+   LoadLibraryEx(LOAD_WITH_ALTERED_SEARCH_PATH).  The function names in this
+   wrapped code are truncated from the long JNICALL names, as JNICALL causes
+   some "@N" with different numeric values for N (and probably different across
+   32 and 64 bit) to be added to the symbol names, which the calls to
+   GetProcAddress in wrapper/wrapper.c would otheriwse have to take into
