Nick Clifton 1181551ef0 Prevent internal assembler errors if a stabs creation function builds an badly formatted input string. 
* read.c (temp_ilp): New function.  Installs a temporary input
	line pointer.
	(restore_ilp): New function.  Restores the original input line
	pointer.
	* read.h (temp_ilp): Prototype.
	(restore_ilp): Prototype.
	* stabs.c (dot_func_p): Use bfd_boolean type.
	(generate_asm_file): Use temp_ilp and restore_ilp.
	(stabs_generate_asm_lineno): Likewise.
	(stabs_generate_asm_endfunc): Likewise.
