Throughout, simplify the C99/C11 conditionals, and replace
__STRICT_ANSI__ with the proper internal POSIX macros. The _*_r
reentrant functions need not be guarded (and most haven't been) because
such names in the global scope are reserved to the implementation.
atoff is unique to newlib.
dtoa is not actually exported (_dtoa_r is used internally), is
nonstandard, and the declaration conflicts with the code included in
MySQL, NSPR, and SpiderMonkey.
mktemp was removed in POSIX.1-2001.
The qsort_r declarations are reordered so that the GNU version retains
precedence.

Import some <stdlib.h> function declarations from latest FreeBSD and
implement them. I am not sure if we should call the global reent
cleanup in quick_exit() similar to exit().

find -name '*.h' |xargs grep -i 'attribute.*(([a-z]'
For an example of the type of bugs this causes, try compiling this valid
C11 program (it's valid because 'noreturn' is reserved for use in the
user namespace unless you include <stdnoreturn.h>):
$ cat foo.c
#define noreturn __attribute__((noreturn))
#include <stdlib.h>
$ gcc -c -o foo.o -Wall foo.c
In file included from /usr/include/stdlib.h:11:0,
from foo.c:2:
