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.
