+XCOMM This makes the glxProxy subdirectory much less noisy, with respect
+XCOMM to warngings.  The code is automatically generated, so we just want
+XCOMM to shut the compiler up at this point.  However, some of the suppressed 
+XCOMM warnings may point to real errors, so they should be investigated at
+XCOMM some time in the future.
