* config/djgpp/djconfig.sh: Add copyright notice.
* ser-go32.c (rawclock): Remove prototype; include time.h instead. (ISR, dos_hookirq, isr_t): Convert K&R definition to ANSI C. (top level) <string.h>: Include gdb_string.h instead. (dos_noop, dos_raw, dos_noflush_set_tty_state) (dos_print_tty_state, dos_info): Remove ATTRIBUTE_UNUSED. * go32-nat.c (go32_create_inferior): Move the declaration of `environ' to here from the top level. (top level) <_initialize_go32_nat>: Remove redundant prototype. <gdb_string.h>: Include it instead of string.h. (store_register): Call register_buffer instead of accessing registers[] directly. (redir_cmdline_delete, redir_cmdline_parse, redir_to_debugger) (redir_to_debugger, redir_debug_init) [__DJGPP_MINOR__ < 3]: Put the function names at the start of the line. (go32_set_dr): Throw internal_error if the argument is not a valid debug register number. (go32_open, go32_close, go32_attach, go32_detach, go32_resume) (go32_wait, go32_xfer_memory, go32_files_info) (go32_terminal_info): Remove ATTRIBUTE_UNUSED.
