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.
