PS. I've got a work around for now... I edited the file "ogr/ogrsf_frmts/vfk/vfkdatablock.cpp" and commented out the lines that referenced "clock()", and the debug line which appears to be all that was using it.
It then built OK. :-) I'm sure you guys can come up with a proper solution, but this did the job for me for now. :-) Cheers, Nik.
