This code seems to have been inserted by Tom Lockhart on 1997-07-29
(geo_ops.c rev 1.13).  Tom, any info on the copyright status?

Per the comments in that thread, it would be pretty trivial to either
rewrite or remove this file.  I don't think there is anything there that
amounts to protectable content (and Mumit evidently agrees, see link)
but let's do something about it anyway.  Can some of the Windows folk
check whether we can just remove it?

This code was added by Michael Meskes in informix.c rev 1.6
(2003-05-06).  Michael, any info on the exact copyright status?
