* assert/assert.h (assert): Rewrite assert's definition so that
a s/==/=/ typo, e.g., assert(errno = ENOENT) is not hidden from
gcc's -Wparentheses by assert-added parentheses.  The new definition
uses "if (expr) /* empty */; else __assert_fail...", so
gcc -Wall will now detect that type of error in an assert, too.
The __STRICT_ANSI__ disjunct is to make this work also with both
-ansi and  -pedantic, which would reject the use of ({...}).
I would have preferred to use __extension__ to mark that, but
doing so would mistakenly suppress warnings about any extension
in the user-supplied "expr".
E.g., "assert ( ({1;}) )" must continue to evoke a warning.

	[BZ #18604]
	* assert/assert.h (assert): Don't macro-expand failed assertion
	expression in error message.
	* malloc/malloc.c (assert): Likewise.

* misc/sys/cdefs.h (_Static_assert): Define a substitute, if on a
pre-C11 C platform that is not known to support _Static_assert.
