	Random fixes.  E.g., (random) never returned negative values.
	* fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
	subseconds part to the entropy, as that's a bit more random.
	Prefer signed to unsigned, since the signedness doesn't matter and
	in general we prefer signed.  When given a limit, use a
	denominator equal to INTMASK + 1, not to VALMASK + 1, because the
	latter isn't right if USE_2_TAGS_FOR_INTS.
	* sysdep.c (get_random): Return a value in the range 0..INTMASK,
	not 0..VALMASK.  Don't discard "excess" bits that random () returns.

	Qgnutls_bootprop_verify_hostname_error, an error for
	Qgnutls_bootprop_verify_error (which is no longer used).

271 272 273 274
	* eval.c (find_handler_clause): Remove parameters `sig' and `data',
	unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca.  All callers changed.
	Also (re)move comments that are misplaced or no longer relevant.

2011-07-01  Paul Eggert  <eggert@cs.ucla.edu>

	* eval.c (struct backtrace): Simplify and port the data structure.
	Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
	signed bit field, as this assumption is not portable and it makes
	Emacs crash when compiled with Sun C 5.8 on sparc.  Do not use
	"char debug_on_exit : 1" as this is not portable either; instead,
	use the portable "unsigned int debug_on_exit : 1".  Remove unused
	member evalargs.  Remove obsolete comments about cc bombing out.

	The following patches are for when GLYPH_DEBUG && !XASSERT.
	* dispextern.h (trace_redisplay_p, dump_glyph_string):
	* dispnew.c (flush_stdout):
	* xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):

	Now static.
	(debug_method_add): Use va_list and vsprintf rather than relying
	on undefined behavior with wrong number of arguments.
	(dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
	Don't assume ptrdiff_t and EMACS_INT are the same width as int.
	In this code, it's OK to assume C99 behavior for ptrdiff_t formats
	since we're not interested in debugging glyphs with old libraries.

	GCC 4.6.0's static checking.

	Use memcpy, not strncpy, where memcpy is what is really wanted.
	Don't assume (via atoi) that time_t and pid_t fit in int.
	Check for time_t and/or pid_t out of range, e.g., via a network share.

	This didn't break anything, but it didn't help either.

762 763 764
	(struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.

	(XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,

	The previous code was bogus.  For example, next_almost_prime (32)

946 947 948 949
	Variadic C functions now count arguments with ptrdiff_t.
	This partly undoes my 2011-03-30 change, which replaced int with size_t.
	Back then I didn't know that the Emacs coding style prefers signed int.
	Also, in the meantime I found a few more instances where arguments
950 951
	were being counted with int, which may truncate counts on 64-bit
	machines, or EMACS_INT, which may be unnecessarily wide.

	* callint.c (Fcall_interactively): Check arg count for overflow,
	to avoid potential buffer overrun.  Use signed char, not 'int',
	for 'varies' array, so that we needn't bother to check its size

	Without this fix, on a 64-bit host (aset S 0 4294967386) would
