* breakpoint.c (breakpoint_re_set_one): Fix storage leak.

Browse Source 
* breakpoint.c (enable_breakpoint): Don't enable watchpoint if it
	went out of scope.
	* exec.c (exec_close): Fix storage leak.
	* exec.c (exec_file_command): Make sure that bfd doesn't realign the
	output sections when patching an executable.
	* mips-nat.c (store_inferior_registers): Use REGISTER_PTRACE_ADDR
	when writing all registers.
	* mips-tdep.c (mips_push_dummy_frame): Save floating point registers
	at the right offset in the dummy frame.
	* mipsread.c (psymtab_to_symtab_1): Do not complain for stProc,
	stStaticProc and stEnd symbols as they are generated by gcc-2.x.
	* mipsread.c (mipscoff_new_init): Initialize stabsread and buildsym.
