+/* This comment is a kludge to get metaconfig to see the symbols
+    VAL_O_NONBLOCK
+    VAL_EAGAIN
+    RD_NODATA
+    EOF_NONBLOCK
+   and include the appropriate metaconfig unit
+   so that Configure will test how to turn on non-blocking I/O
+   for a file descriptor.  See config.h for how to use these
+   in your extension. 
+   
+   While I'm at it, I'll have metaconfig look for HAS_POLL too.
