Native windows ODBC support for mingw64 compile

[robe]

As mentioned in my blog entry -

​http://www.bostongis.com/blog/index.php?/archives/237-Building-GDAL-under-mingw-w64-with-native-windows-ODBC-support.html

there is no current way (at least not one I could find) that allows building ODBC with native windows ODBC under mingw64 without hacking the configure script. I'm working on a patch to do that and think I have it almost ready to commit once I've gotten it working with mingw64-w32. The way it works is that if --with-odbc is selected and it finds the odbc windows bindings (but not the others), it will use the odbc windows bindings. So it's not so specific to mingw64.

Any update on this ?

Attached is a patch for 2.0 and 2.1 branch. I also tested on Debian 7 that has UnixODBC to make sure it didn't clubber configure on that.

This I tested with mingw64-w64 and mingw64-w32 chains.

I've slightly modified your patch. Please check it still works for you. If so, I'll backport it

trunk r33619 "configure: add support for ODBC autodetection with mingw64 (derived from patch by Regina Obe, #6000)"

Yap still works on both my 64bit and 32-bit builds.
