Changes from Fred Fish:
* tm-68k.h (FPI_REGNUM): Add. * infrun.c (child_create_inferior): flush stdout and stderr before forking. * configure.in: Handle amigados, amix hosts and targets. * inflow.c: Handle TIOCGLTC_BROKEN for Amiga. From Andreas Schwab: * values.c (show_convenience): Use printf_filtered. * main.c (define_command): Check result of lookup_command for exact match. (echo_command): Use printf_filtered, and force output out. * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C programs. * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended. * utils.c (_initialize_utils): If !ISATTY, don't paginate.
