Three of the bit twiddling routines are exported to
@code{gdb}; @code{coff_swap_aux_in}, @code{coff_swap_sym_in}
- and @code{coff_swap_linno_in}. @code{GDB} reads the symbol
+ and @code{coff_swap_lineno_in}. @code{GDB} reads the symbol
table on its own, but uses BFD to fix things up. More of the
bit twiddlers are exported for @code{gas};
