Compiling on SCO

I'm attempting to compile 7.0.2 on a SCO box. The compile fails attempting to
build ecpg, complaining that nocachegetattr is undefined, first referenced in
pgc.o

I'm unable to find any reference to this. I used the configure options
described in the FAQ_SCO file along with --with-odbc but to no avail.

Does anyone have any suggestions as to what I might look for.

Thanks, Scott
