<body>I think ST_DFullyWithin sounds great.<br />
Is it ok if I put this to in ticket #137. In the code they are all close related, st_distance, st_max_distace, st_shortestline, st_longestline, st_dwithin, st_dfullywithin<br />
<br />
I have a patch for the trunk that seems to work, but I haven't tested more than randomly. I will try to build cunit-tests but I think it is difficult to get the make check thing work at all. In windows I get som problems and in ubuntu I get permission-problems. I'm new to Linux.<br />
<br />
I also just have become a father :-) two weeks ago so my sparetime for learning new things has drastically decreased. <br />
