OK, in that case I'm sorry for being right :-)
No, short of digging into the LCD_Bar include file and replacing the code that is using the DIV32 macros with code that doesn't there is no solution.

When you're using LONGs there's no need for the DIV32 command so it's not included in the LONG-enabled version of library files. It MIGHT be possible to "hack" them back in but I don't know how to do that.

Without ever having looked at the LCD_Bar file(s) I think rewriting those is your best bet.
