* Makefile.in (gdb_select_h, ser_tcp_h): New. (ALLDEPFILES): Add ser-mingw.c. (event-loop.o, inflow.o, mingw-hdep.o, posix-hdep.o, ser-base.o) (ser-tcp.o, ser-unix.o): Update. (ser-mingw.o): New rule. * configure: Regenerated. * configure.ac: Add ser-mingw.o for mingw32. * ser-mingw.c: New file. * event-loop.c: Include "gdb_select.h". (gdb_select): Remove, moved to mingw-hdep.c and posix-hdep.c. * ser-base.c: Include "gdb_select.h". (ser_base_wait_for): Use gdb_select. * serial.c (serial_for_fd): New function. (serial_fdopen): Try "terminal" before "hardwire". Initialize the allocated struct serial. (serial_wait_handle): New function. * serial.h (serial_for_fd, serial_wait_handle): New prototypes. (struct serial_ops) [USE_WIN32API]: Add wait_handle. * gdb_select.h: New file. * ser-tcp.c: Include "ser-tcp.h". Remove unused "ser-unix.h" include. (net_close, net_read_prim, net_write_prim): Make global. (net_open): Likewise. Pass an exception set to select. Whitespace fix. Document why we can not use gdb_select. (_initialize_ser_tcp) [USE_WIN32API]: Do not register TCP support here. * ser-tcp.h: New file. * inflow.c (gdb_has_a_terminal): Don't initialize stdin_serial here. (handle_sigio): Use gdb_select. (initialize_stdin_serial): New function. * terminal.h (initialize_stdin_serial): New prototype. * top.c (gdb_init): Call initialize_stdin_serial. * mingw-hdep.c (gdb_select): New function, moved from gdb_select in event-loop.c. Add exception condition support. Use serial_for_fd and serial_wait_handle. Fix timeout handling. * posix-hdep.c: Include "gdb_select.h". (gdb_select): New function. * remote-st.c (connect_command): Use gdb_select. * ser-unix.c: Include "gdb_select.h". (hardwire_send_break, wait_for): Use gdb_select.
