mdbtools: [PATCH] Fixes in odbc.c to return size of returned strings and handle OLE data

[Even Rouault]

Package: mdbtools
Version: 0.5.99.0.6pre1.0.20051109-4
Severity: important

I've also reported it on Fedora's bugzilla as 
https://bugzilla.redhat.com/show_bug.cgi?id=472692

A Fedora maintener has reviewed the patch and proposed a revised version which 
I agree about. As he was the first one of the distro's mainteners to react, 
I'd propose that the potential further discussions take place over there. :-)

Anyway, I'm attaching that revised version to that email.

Best regards
