* monitor.c (monitor_printf): Changed format specification in

  error message to work with pre-ansi compilers.
  (monitor_load_srec): reduced length of s-records from 128 to 32
  bytes so download is more reliable with the rom68k monitor.

* rom68k-rom.c: Added trailing space to prompt string.

* config/i386/xm-i386sco.h (HAVE_STRSTR): Removed.
* config/i386/xm-go32.h, mswin/xm.h (SYS_SIGLIST_MISSING):
  Removed.
* defs.h, config/{xm-lynx.h, xm-nbsd.h},
  config/i386/{xm-i386bsd.h, xm-linux.h},
  config/m68k/xm-hp300bsd.h, config/mips/xm-irix4.h,
  config/ns32k/xm-ns32km3.h, doc/gdbint.texinfo
  (PSIGNAL_IN_SIGNAL_H): Removed.
