	* ftfont.c: Distingish more carefully between FcChar8 and char.
	The previous code passed unsigned char * to a functions like

	Report overflow in size calculations when allocating printf buffer.
	Do not truncate output string at its first null byte.
	* xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
	Truncate the output at a character boundary, since vsnprintf does not

	character to string before calling 'error', since %c now has the
	printf meaning.

	overflow when computing char to be passed to 'error'.  Do not

	* coding.c (encode_coding_raw_text): Avoid unnecessary test

	This also avoids a gcc -Wstrict-overflow warning.

1304 1305 1306
	* lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
	leading to a memory leak, possible in functions like
	load_charset_map_from_file that can allocate an unbounded number
