What is DirectBits? Help!

[Ty Brower]

  I'm trying to build using the R6 Beta with PalmOS 3.1 support.  I've got
PalmGlue.lib included and I'm using the TxtGlue API's.  Everything compiles
fine, but at the end of the link stage CodeWarrior complains:  "Link Error:
DirectBits not supported"  I can't find any mention of DirectBits in the
documentation or headers.  What is it?  How am I using it that it's not
supported?
