* objc/objc-act.c (dump_interface): Enlarged the char * buffer to
10k. Fixed category dumping - print out category names with the
proper syntax. Print '@end\n' and not '\n@end' at the end of the
interface.
(finish_objc): Fixed the -gen-decls option. It was printing out
only the last class. Dump an interface declaration of all classes
being compiled instead.

* config/arm/arm-protos.h (arm_gen_return_addr_mask): New
