Some changes to eliminate warnings with Apple clang version 1.7. src/ChangeLog addition: 2014-10-18 Aidan Kehoe <kehoea@parhasard.net> Some changes to eliminate warnings with Apple clang version 1.7. * cm.c (send_string_to_tty_console): * doprnt.c (doprnt_2): * doprnt.c (parse_off_posnum): * event-stream.c (dribble_out_event): Cast various calls to Lstream_putc() to void when the result isn't being used, for the sake of clang. * lisp.h: Declare #'replace here too, it's used in event-stream.c. * lisp.h (ALLOCA): * lisp.h (MALLOC_OR_ALLOCA): Cast a couple of zeros in the context of the ternary operator to void to prevent unused value warnings with clang. * sysdep.c (child_setup_tty): * text.h (ASSERT_ASCTEXT_ASCII_LEN): Use DO_NOTHING in these files to quieten the compiler. lib-src/ChangeLog addition: 2014-10-18 Aidan Kehoe <kehoea@parhasard.net> * ootags.c (substitute): Cast the result of strlen to int before comparing it with a signed value, for the sake of compiler warnings.
