that directory. * defs.h utils.c (error warning): Make message be const. * main.c (fputs_unfiltered): Only send gdb_stdout and gdb_stderr to hook. Otherwise send it to fputs. * monitor.c monitor.h (monitor_get_dev_name): New function. Does the obvious. * remote-e7000.c: Remove debugify stuff. Change printf, fprintf to _filtered forms to make output appear in GUIs. Replace all uses of SERIAL_READCHAR with readchar, which has better error checking. * (e7000_parse_device): Add prototype. * (readchar): Improve doc. Handle random serial errors. * (expect): Disable notice_quit code. It's busted. Remove serial error handling (it's now handled in readchar). Remove remote_debug echoing. That's handled in readchar as well. * (e7000_parse_device): Remove serial_flag arg. It's not necessary. * (e7000_open): Split into two pieces. Second part is e7000_start_remote, and is error protected. Now, when we connect to the target, we setup the initial frame and registers so that the user gets an immediate indication of where the target is. * (gch): Remove debug output. That's handled by readchar. * (e7000_read_inferior_memory): Handle errors better. * (_initialize_remote_e7000): Get rid of `<xxx>' things from command names. They show up when doing completion and confuse things horribly. * ser-e7kpc.c: Remove the last seven months of brain damage. Get rid of the DLL's since we can access the device directly from Win32s and Win95. Get rid of debugify crud. * serial.c: Remove debugify cruft. * (serial_logchar serial_log_command serial_write serial_readchar serial_send_break serial_close): Merge common functionality into serial_logchar. Clean up rest of routines. * sparclet-rom.c: Disembowel. Leave only download routine. Download routine now switches to remote target automatically. * top.c (disconnect): Only define if SIGHUP is defined. Cleans up MSVC/Win32 problem. * utils.c (gdb_flush): Don't call hook unless it's for gdb_stdout or gdb_stderr. * config/sh/tm-sh.h: Define TARGET_SH for WinGDB. * config/sparc/tm-sparclet.h: Remove override for prompt.
