The change to the base relative addressing flag is a little confusing.  The
compiler uses base relative addressing by default.  If you want to turn
that off the switch setting is -b0.  It's discussed on page C-19, the
                               ^^^
description of lc1.  The manual says:

-b     Base register relative data addressing.  Note that this [is] now the
       default.  To switch this mode off use -b0 option.  The options -b or
       -b1 will switch base register relative data addressing back on
       again.
