1998-10-06  Jason Molenda  (jsm@bugshack.cygnus.com)

        Eliminate a few warnings from the compiler.
        * breakpoint.h: Add prototype.
        * breakpoint.c (do_enable_breakpoint): cast mem_cnt, i to (void).
        * configure.in: Check if strdup declaration is necessary.
        * configure: Regenerated.
        * defs.h: Add prototypes.
        * gdb_string.h: Only define strdup if necessary.
        * gdbthread.h: Add prototypes.
        * printcmd.c: Add prototyptes.
        (disassemble_command): Remove unused variable 'section'.
        * symtab.c: Add prototypes.
        * symtab.h: Include gnu-regex.h, add prototype.
        * thread.c: Add prototype.
